Manage: Call validate_geometry when adding drive to external container

When adding drive to container call validate_geometry to verify whether
drive is supported and can be addded to container.

Remove unused parameters from validate_geometry_imsm_container().
There is no need to pass them.
Don't calculate freesize if it is not mandatory. Make it configurable.
