Poor performance on Juju local with lxc containers.

[Sebastian]

ha!! gotcha!! finally I know why, the php5-xdebug was installed and enabled
by default, didn't know was such a big impact of performance.

So this is going to the charm's configuration
<https://github.com/sebas5384/charm-drupal>, so can be an option.

Happy Sebas now.
