Create /root/.my.cnf even when root passwd is not managed

[bodepd]

When the root password is not managed, it causes mysql to
fail b/c it does not create the /root/.my.cnf file (which causes
all mysql commands from the provider to fail)

I updated my submodule to this version and Mysql fails:

Could not find dependency Exec[set_mysql_rootpw] for File[/root/.my.cnf] at /tmp/vagrant-puppet/modules-0/mysql/manifests/config.pp:123

@alombarte Thanks so much for the report! Crowd-sourcing at its best :). It looks like #126 may address this.

No, thank you! It works and the /root/.my.cnf is created correctly.
