BaseManager.execute_process fails if connection is not defined

[francescoingv]

Description Using the BaseManager as manager, while it is safe to not define the configuration parameter output_dir, it causes an error if it is not defined the configuration parameter connection.

I think it should be possible to safely use BaseManager also without the connection configuration parameter. All other methods that could benefit from this parameter (get_jobs, add_job, update_job, get_job, get_job_result, delete_job) currently return the proper Error, as they will possibly be implement by the derived classes as required.

Steps to Reproduce Modify the manager section of example-config.yml with the following lines:

    manager:
        name:  'pygeoapi.process.manager.base.BaseManager'

Call a EchoProcessor curl localhost:5000/processes/hello-world/execution -H 'Content-Type: application/json' -d '{"inputs": {"message": "my message,", "name": "My Name"}}' Expected behavior The call produce the following result:

{
    "id":"echo",
    "value":"Hello My Name! my message,"
}

Environment

• OS: Ubuntu
• Python version: 3.8.10
• pygeoapi version: master
