### _Why are the changes needed?_
This PR proposes to enhance the LDAP support, which mainly referring the code introduced in HIVE-14713.
Currently, Kyuubi has very limited LDAP support, and the implementation is from the early Hive codebase. Hive enhanced the LDAP support in later versions, considering the Hive ecosystem is quite mature, I think we'd better to porting this functionality and keep the same behavior w/ Hive first, and we can improve it if meet certain requirements/issues in the future.
Basically, this PR introduces the following configurations
```
kyuubi.authentication.ldap.url (since 1.0.0)
kyuubi.authentication.ldap.domain (since 1.0.0)
kyuubi.authentication.ldap.guidKey (since 1.2.0)
kyuubi.authentication.ldap.base.dn (since 1.0.0 deprecated)
kyuubi.authentication.ldap.baseDN
kyuubi.authentication.ldap.groupMembershipKey
kyuubi.authentication.ldap.userMembershipKey
kyuubi.authentication.ldap.groupClassKey
kyuubi.authentication.ldap.groupDNPattern
kyuubi.authentication.ldap.userDNPattern
kyuubi.authentication.ldap.groupFilter
kyuubi.authentication.ldap.userFilter
kyuubi.authentication.ldap.customLDAPQuery
kyuubi.authentication.ldap.binddn
kyuubi.authentication.ldap.bindpw
```
### _How was this patch tested?_
- [x] Add some test cases that check the changes thoroughly including negative and positive cases if possible
This PR ports all LDAP-related UT&IT from Hive codebase
- [ ] Add screenshots for manual tests if appropriate
- [x] [Run test](https://kyuubi.apache.org/docs/latest/develop_tools/testing.html#running-tests) locally before make a pull request
