Use meta/collection-requirements.yml for collection dependencies (#267)

There is no way for a role to automatically require collections for
module/plugin dependencies. Use the non-standard file
meta/collection-requirements.yml for this. Note that
meta/requirements.yml is supposed to be a list of roles only, in
the format described at https://docs.ansible.com/ansible/latest/galaxy/user_guide.html#installing-multiple-roles-from-multiple-files

add support for mount_options (#270)

• add support for mount_options

When support for argument validation was added, that support did not
include the mount_options parameter. This fix adds back that
parameter. In addition, the volume module arguments are refactored
so that the common volume parameters such as mount_options can be
specified in one place.

This adds a test for the mount_options parameter, and adds
verification for that parameter.

• only checkout mount_options if requested
