Move myrocks settings to my.cnf

Summary:
This enables running myrocks test byitself without relying on any magic from mysqltest.sh, making it easier for external folks to run it. It also enables running myrocks + innodb tests together, useful for cases like code coverage runs, etc.

The idea is to move those settings into my.cnf in myrocks suites and put it in a common file default_rocksdb.cnf.
