Always post model version info on worker startup

Added new environment variable OASIS_DISABLE_WORKER_SETTINGS_REG={True | False}. When set to true a workers model_settings.json file is skipped when a worker connects to a queue.

Example:

OASIS_DISABLE_WORKER_SETTINGS_REG=True   # Only disables sending `model_settings`
OASIS_DISABLE_WORKER_REG=False           # Disables all registration (when true, nothing is sent to the API) 

With the above set when a worker joins a queue it will:

• Check the API for a model entry in the DB (supplier, name, version)
• If not found, creates a new model
• Adds the oasis component versions to the API DB

Example: worker image tagged 1.28.4

curl -X 'GET' 'http://localhost:8000/api/v1/models/2/versions/'
{
  "ver_ktools": "fmcalc : version: 3.11.0 - git update: ",
  "ver_oasislmf": "1.28.4",
  "ver_platform": "1.28.4"
}
