ENG-9909 add support for path-based multi-tenancy

[dfreidin]

Add new support for path-based multi-tenancy, with options in client initialization.

• new base_path parameter to explicitly set the base path for the environment
• ability to extract the base path if a full base url is given at initialization
  • base_path parameter will take precedence
• should be backwards compatible if no path is given

Manual testing can be done against https://sm-nested-path.test.sightmachine.io/nested/one/two/:

from smsdk import client

cli = client.Client('sm-nested-path.test', base_path='/nested/one/two/')

# OR:
# cli = client.Client('sm-nested-path.test.sightmachine.io/nested/one/two/')

cli.login('apikey', key_id='<your_api_key>', secret_id='<your_api_secret'>')

cli.get_machine_type_names()
# ['Packer', 'Palletizer', 'L1 Warmer', 'Electricity', 'Line 1', 'Filtec', 'Wrapper', 'L1-Depal', 'Empty Can Conveyor', 'L1 Case Conveyor', 'Filler', 'L1 Full Can Conveyor', 'Blender_1']

Also fixed some tests that were already failing in master. Most of these are due to the fact that it queries for data in the demo environment, and the data available has changed at some point. The final failing test, test_get_line_data, is an actual bug in MA, fixed with https://github.com/sightmachine/ma/pull/8631 .

Do we want pycoverage reports event if we do not do pycov? The MA report supports both reporting so that can be referenced.
