### What changes were proposed in this pull request?
Add config to limit max workers when offering slots, the config can be set both
in server side and client side. Celeborn will choose the smaller positive configs from client and master.
### Why are the changes needed?
For large Celeborn clusters, users may want to limit the number of workers that
a shuffle can spread, reasons are:
1. One worker failure will not affect all applications
2. One huge shuffle will not affect all applications
3. It's more efficient to limit a shuffle within a restricted number of workers, say 100, than
spreading across a large number of workers, say 1000, because the network connections
in pushing data is `number of ShuffleClient` * `number of allocated Workers`
The recommended number of Workers should depend on workload and Worker hardware,
and this can be configured per application, so it's relatively flexible.
### Does this PR introduce _any_ user-facing change?
No, added a new configuration.
### How was this patch tested?
Added ITs and passes GA.

### What changes were proposed in this pull request?
Add heartbeat from client to lifecycle manager. In this PR heartbeat request contains local shuffle ids from
client, lifecycle manager checks with it's local set and returns ids it doesn't know. Upon receiving response,
client calls ```unregisterShuffle``` for cleanup.
### Why are the changes needed?
Before this PR, client side ```unregisterShuffle``` is never called. When running TPCDS 3T with spark thriftserver
without DRA, I found the Executor's heap contains 1.6 million PartitionLocation objects (and StorageInfo):
After this PR, the number of PartitionLocation objects decreases to 275 thousands
This heartbeat can be extended in the future for other purposes, i.e. reporting client's metrics.

### Why are the changes needed?
