Review Comment:
I think making the history length configurable via optional input parameter
makes sense. We'd still want a configuration for the default length (ie. 50)
when the parameter is not specified. This could be an environmental variable or
a
[cqlshrc](https://docs.datastax.com/en/dse/5.1/cql/cql/cql_reference/cqlsh_commands/cqlshCqlshrc.html)
configuration. Perhaps we can start with an environment variable and later
expand to allow the default size to be specified in `cqlshrc` ?
