The report host status is agnostic to error codes

[dsmolyarenko]

Describe the issue
Currently the HostStatus.ConnectFail status is being set on following exceptions attempting to obtain connection:

1. ConnectException
2. IOException
3. SQLException

See ConnectionFactoryImpl#openConnectionImpl method. Setting this status the host is excluded from the hosts list for a certain number of seconds (hostRecheckSeconds property).
The problem that some error codes doesn't mean the host needs to be marked as unavailable. The example is 53300 - that means user role connection limit is reached. This means that another role still eligible to establish a connection but the host is halted for seconds.

      } catch (SQLException se) {
        closeStream(newStream);
        GlobalHostStatusTracker.reportHostStatus(hostSpec, HostStatus.ConnectFail);
        knownStates.put(hostSpec, HostStatus.ConnectFail);
        if (hostIter.hasNext()) {
        ...

Driver Version?
42.7.3

Java Version?

OS Version?
rhel 9

PostgreSQL Version?
13.9

To Reproduce
Configure multihost jdbc url with two or more hosts.

Expected behaviour
Certain error codes shouldn't mark hosts as broken:

      } catch (SQLException se) {
        closeStream(newStream);
        if (isConnectFailure(se.getSQLState())) { // it needs to check a driver property with error codes list
            GlobalHostStatusTracker.reportHostStatus(hostSpec, HostStatus.ConnectFail);
        }
        knownStates.put(hostSpec, HostStatus.ConnectFail);
        if (hostIter.hasNext()) {
        ...
