[Impala-ASF-CR] WIP IMPALA-12060: Only allow a single catalog instance in a cluster

WIP IMPALA-12060: Only allow a single catalog instance in a cluster
Impala doesn't support multiple catalogd instances to be part of
a cluster. When using external Active Passive HA mechanisms like
leader election, it may be possible for multiple catalog instances
to be added in one cluster, in some cases.
This patch fixs the issue by using statestore to ensure that there
could only be a single instance of catalogd to be registered in a
cluster. When a statestore subscriber in recovery mode, it will
resolve its heartbeat address before re-registering to statestore.
This prevents catalogd in passive mode from attempting to join the
cluster.
Testing:
- Passed the core tests.
- TODO unit-test
