Support for symlink data dirs

[danir-de]

Hey there.
I've been managing a bigger nextcloud instance and stumbled upon a problem while migrating data from the native data folder to a symlink of another folder.

In our exact scenario, we want to use another path (for example /mnt/nextcloud) and make a symlink from /opt/nextcloud-data to /mnt/nextcloud.
The problem in this being, that the puppet module doesn't allow me to define another folder or symlink, since that directory is already a defined object:

puppet-nextcloud/manifests/install.pp

Lines 7 to 12 in d5be5c7

	file { $nextcloud::datadir:
	ensure => directory,
	owner => $nextcloud::system_user,
	group => $nextcloud::system_group,
	before => Nextcloud::Install::Distribution['initial install'],
	}

It would be great to have a toggle, that allows me to "skip" the automatic creation of the data folder in order to define my own puppet file element with a toggle like manage_datadir => false.
