Pin  mysql to major version for fixtures

Previously, unit tests were using master for testing.

This commit changes them to use the newly created major version
branches. This allows us to backport bug fixes while we wait for
upstream to stabilize.

Update allowed_hosts conditional statement

In the origin keystone::db::mysql, if the value of $allowed_hosts
contains or equals to $host, then puppet will complain duplicate
declaration error. This patch is aim to update the allowed_hosts
conditonal statement in keystone::db::mysql.

There are two cases to pass $allowed_hosts to $real_allowed_hosts:

   - If $allowed_hosts is array,then remove $host from $allowed_hosts;
   - elsif $allowed_hosts is string and not equivalent to $host;

At last, if $real_allowed_hosts is not undef, then run
keystone::db::mysql::host_access
