Description

User on GH sent:

I just started using cassandra and found that it creates history folder in my home directory. I personally don't like it and all my folders follow XDG standard. I found stackoverflow question related to it which says that it's not possible to do without configuring source code of cqlsh.py.

In this pull request I added a feature to choose history directory using environment variable. The name of variable is CQL_HISTORY. Why ? Because postgres and node-repl use approximately the same convention (NODE_REPL_HISTORY,PSQL_HISTORY). If you want I can change the name.
