Pavel Yaskevich updated CASSANDRA-3842:
---------------------------------------

    Attachment: CASSANDRA-3842.patch

saves the file with CLI schema definitions and then just displays it's contents to the user + prints the name of the file for later use.

Format of the file name "schema[-<keyspace>]-<timestamp>.cli"

[-keyspace] part is only added when `show schema` was executed while one of the keyspaces was selected using `use <keyspace>` command.

> Primary use-case for `show schema` is to persist current schema to load it later (possibly on the other machines), so if we output it into timestamped file this would make a good bonus in usability.
