Add support to add tags to the ClearML task via build_options

[pmachapman]

Fixes sillsdev/serval#709

This PR adds support for specifying tags via build_options, for example:

from machine.jobs.build_smt_engine import run
args = {
    'model_type': 'thot',
    'engine_id': '6848db0e6062343fa1d3a472',
    'build_id': '687715134a39e1ae2909b94d',
    'shared_file_uri': 's3://silnlp',
    'shared_file_folder': 'docker-compose/',
    'build_options': '''{"tags":"sf-dev"}''',
    'clearml': True
}
run(args)

The job in ClearML then will display as follows:

The build options will be configured in Scripture Forge. No change to Serval is required.

I like this a lot 😁
