Tomasz Grabiec 8297ae531d Merge "Automatically retry CQL DDL statements in presence of concurrent changes" from Kamil

Schema changes on top of Raft do not allow concurrent changes.
If two changes are attempted concurrently, one of them gets
`group0_concurrent_modification` exception.

Catch the exception in CQL DDL statement execution function and retry.

In addition, improve the description of CQL DDL statements
in group 0 history table.

Add a test which checks that group 0 history grows iff a schema change does
not throw `group0_concurrent_modification`. Also check that the retry
mechanism works as expected.

* kbr/ddl-retry-v1:
  test: unit test for group 0 concurrent change protection and CQL DDL retries
  cql3: statements: schema_altering_statement: automatically retry in presence of concurrent changes
