Tab completion in cqlsh doesn't work for capitalized letters

[Mahdi Mohammadi]

Regarding CASSANDRA-11664
<https://issues.apache.org/jira/browse/CASSANDRA-11664>:

I checked this issue and seems it's because in Parser.g file for ANTLR we
have specified that casing should not be preserved for keyspace name
identifiers which are not quoted:

t=IDENT              { $name.setKeyspace($t.text, false);

t=IDENT              { $name.setColumnFamily($t.text, false);


In order to solve this , I will need to change this behavior. Any
objections?

Best Regards
