[FLINK-3299] Remove ApplicationID from Environment
As per discussion in the issue, we decided to remove the the
`ApplicationID`.
Replaces the app ID in RocksDB and DB backend with job ID. I've talked to
@gyfora about the DB backend and he mentioned a possible problem with
savepoints in certain corner cases, but all in all the change should be OK.

>
> {{ApplicationID}} is used to identify an application across many job
> submissions (for example after restoring from a savepoint). This is currently
> exposed in the {{Environment}}, which might be unnecessary.
> State backends, which need the ID can generate it themselves and store it as
> part of their state handle.
> This has to be checked with the DB state backend, which currently uses this.
