update: do not enforce `serial: 1` on client nodes 

There is no need to enforce `serial: 1` on client nodes.
Let's make it parameterizable by introducing a new *extra* variable
`client_update_batch`, if not filled this will default to `{{
ansible_forks }}`.

NOTE: this is only usable as an extra variable passed with
`-e client_update_batch=<num>`
