See ticket
https://issues.redhat.com/browse/DBZ-8541

If we have the task with shards
s1: current
s2: current

Then the first vgtid we will receive will be (this would cause an exception with current code, even though it's valid)
s1: gtid1
s2: current

Then at some point we will get a transaction for s2 as well and will be
s1: gtid1
s2: gtid2

Adapt our logic to gracefully handle these partially overridden VGTIDs.

Also do some miscellaneous improvements

Simply vitess epoch provider logic
Add tests for gtid, remove unnecessary methods
Make validation & other checks more thorough
Make handling more general so we fail less often
Add more tests for above case and others
