Add server license option to switch between read only and read/write

[dkowollik]

📝 Description of the feature

It would be great to have a similar license behaviour comparable to the Workbench, where the Services like Mechanical and SpaceClaim can change from read/write mode to read only and back. This is extremely useful to get rid of the launch and exit overhead that is included in each service. Parameter variations with a workflow of four to five pyansys packages need too many preppost licenses in parallel.

A read only option might not be necessary, if you organize the check_in and check_out of licenses differently. A method license_check_in() and license_check_out() added to the prime client object would be sufficient. Python packages like PyACP use check in and check out only during an update call. I can understand, if you think that this is too much overhead. For me it would be sufficient to be able to call license_check_in() at the end of an update loop, before I continue the update with a different pyansys service.
