Kamil Braun edd8344706 cql3: statements: schema_altering_statement: automatically retry in presence of concurrent changes
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, the description of CQL DDL statements in group 0 history
table was improved.
