Expose task commands

[FedericoNegri]

Exposing commands as available in the JMS API:

• adding task command definition and task commands schemas + resources
• exposing corresponding api endpoints in the ProjectApi class:
  • get_task_command_definitions, get_task_commands and create_task_commands are the usual minimal wrapper around the REST endpoints
  • queue_task_command is a helper function to easily send a command to a task (it mimics what a user does in the web ui), for example:

    command = project_api.queue_task_command(task.id, "my_command", arg1=6.5, arg2="test")

• changes in the src/ansys/hps/client/jms/resource folder are due to a different header used to auto-generate JMS resources
• will follow up with some doc (user guide and/or an example)
