docs/devel: add 'deploy to minikube' docs
**What this PR does / why we need it**:
I felt that the steps to deploy/run/test cert-manager in minikube were non-trivial enough that it was worth documenting.
Let me know if this should live somewhere else in the repo or if you have suggestions for how to better document this.

Fix .gitlab-ci.yml build
Since #372 merged, builds of master (which lead to releases) have been failing.
Technically, the PULL_BASE_SHA should be set to the SHA value of the branch this PR is being *merged into*. Because we don't actually test these on GitLab, this workaround is okay (setting it to the value of the current commit).

Use Google's DNS IPs instead of domain
**What this PR does / why we need it**:
If /etc/resolv.conf does not have any entries, then its unlikely
that the domain name representation of google's DNS would get
resolved too. Hence using IP address directly makes sense.

**What this PR does / why we need it**:
Since #352 merged, we now use the k/charts chart in the deployment guide. This PR updates our deploying docs to reflect the options on the upstream k/charts chart.
It also removes some old and unused deployment files to reduce confusion for new users.

Add Endpoints back into the cert-manager RBAC policy
**What this PR does / why we need it**:
Adds permission to CRUD Endpoints resources back into the cert-manager RBAC role. This is to prevent deployments using the 'master' version of the Helm chart failing when deploying a pre-0.3 (unreleased) release of cert-manager.
We will remove this in 0.4. This is in order to reduce friction for new users if they forget/decide not to use a tagged release of the Helm chart.

```release-note

Set default cluster resource namespace to current pod namespace
**What this PR does / why we need it**:
Changes the default cluster resource namespace from kube-system to the current namespace of the cert-manager deployment.
**Which issue this PR fixes**: fixes#103
**Release note**:
```release-note
Supporting resources for ClusterIssuer's (e.g. signing CA certificates, or ACME account private keys) will now be stored in the same namespace as cert-manager, instead of kube-system in previous versions. Action required: you will need to ensure to properly manually migrate these referenced resources across into the deployment namespace of cert-manager, else cert-manager may not be able to find account private keys or signing CA certificates.

Update default deployment namespace to be 'cert-manager'

Rename Event types to be prefixed 'Err' instead of 'Error' for brevity
**What this PR does / why we need it**:
Shortens the event type names we use to be prefixed 'Err' instead of 'Error'

Make existing TLS certificate check emit a Normal event instead of Warning when the existing certificate is invalid
**What this PR does / why we need it**:
Previously, when requesting a certificate for the first time, the following events are logged:
```
Warning ErrorCheckCertificate 1m cert-manager-controller Error checking existing TLS certificate: secret "httpbin" not found
Normal PrepareCertificate 1m cert-manager-controller Preparing certificate with issuer
```
This has caused confusion for users when they see a Warning/Error being logged. This PR changes that to be:
```
Normal ErrorCheckCertificate 1m cert-manager-controller Error checking existing TLS certificate, will re-issue: secret "httpbin" not found
Normal PrepareCertificate 1m cert-manager-controller Preparing certificate with issuer
```
**Release note**:
```release-note
Clearer event logging when issuing a certificate for the first time

Add default shortNames to certificates CRD
Defaults to `[cert, certs]` and is configurable with `certificateCRDShortNames` parameter.
**What this PR does / why we need it**:
Simplifies manual certificate management with kubectl.
Fixes#311
<div name="review-notes" />
**Special notes for your reviewer**:
Instead of a boolean switch do/dont include the shortNames, the value defines the aliases. This may be handy if anybody prefers `[crt, crts]` instead.
I'm not too keen on the `certificateCRDShortNames` variable name. It might be better to use `Resource` instead of `CRD` to be consistent with the `createCustomResource` var.
Other CRDs are probably ok without an alias, but other people workflows may differ. Should these also be configurable? In that case, the variables could be `shortNames: {certificates: [], …}`.
**Release note**:
```release-note
Add Certificate CRD shortnames `cert` and `certs`. This is configurable in the Helm Chart with `certificateResourceShortNames`.

Check the value of the tls-acme annotation, not just its existence
**What this PR does / why we need it**: Previously the ingress-shim would sync an Ingress resource if it simply contained the `kubernetes.io/tls-acme` annotation, regardless of the value; now it will only do so if the annotation value is truthy (e.g., "true", "t", "1", so forth).
**Special notes for your reviewer**: This could probably be done in a way that doesn't disrupt the function's aesthetics so much. Open to all suggestions.
**Release note**:
```release-note
ingress-shim will only sync Ingress resources with `kubernetes.io/tls-acme` annotation if the value of that annotation is true.

Bundle the CA public key in issued certificate
**What this PR does / why we need it**:
If the CA used is only an intermediate CA, and the root CA is trusted by the client, the client needs help verifying the certificate chain.
This also makes the CA present in the certificate even if it's the root CA.
**Which issue this PR fixes**:
Trusting certs issued by intermediate CAs used by cert-manager.
**Special notes for your reviewer**:
I have tested this locally with my own intermediate CA used by cert-manager, issued by my own root CA trusted by my macOS client. The whole certificate chain is now presented in the browser.
The idea to just append the certificates is based on cfssl's mkbundle:
https://github.com/cloudflare/cfssl/blob/1.3.0/cmd/mkbundle/mkbundle.go#L97
**Release note**:
```release-note
CA Issuer: bundle CA certificate with issued certificates
```
