Review comment:
Let's move the exception handling at the very end. That way we can also
catch if `confirmLeaderSessionID` fails. In all cases, we should call
`onFatalError`.

> Mesos resource manager unable to connect to master after failover
> -----------------------------------------------------------------
>
> Key: FLINK-9936
> URL: https://issues.apache.org/jira/browse/FLINK-9936
> Project: Flink
> Issue Type: Bug
> Components: Mesos, Scheduler
> Affects Versions: 1.5.0, 1.5.1, 1.6.0
> Reporter: Renjie Liu
> Assignee: Gary Yao
> Priority: Blocker
> Labels: pull-request-available
> Fix For: 1.5.3, 1.6.0
>
>
> When deployed in mesos session cluster mode, the connector monitor keeps
> reporting unable to connect to mesos after restart. In fact, scheduler driver
> already connected to mesos master, but when the connected message is lost.
> This is because leadership is not granted yet and fence id is not set, the
> rpc service ignores the connected message. So we should connect to mesos
> master after leadership is granted.
