Test(cv_deploy): Add support for offline testing of CVClient

[ClausHolbechArista]

Change Summary

Add support for offline testing of CVClient

Proposed changes

• Create a recorder for API requests coming from CVClient.
• Create a mock class to play back the recorded responses.
• Various mockery to make cvclient happy in offline state.

How to test

Added a pytest fixture which automatically serves the relevant type of CVClient:

@pytest_asyncio.fixture
async def cv_client() -> AsyncGenerator[CVClient, None]:
    """
    Instance of CVClient.

    If CVAAS_AAWG_CI environment variable is set, but RECORDING environment variable is not set,
    this will return a proper instance of CVClient connected to cv-staging with the token.

    If CVAAS_AAWG_CI environment variable is set, but RECORDING environment variable is set,
    this will return an instance of CVClient connected to cv-staging with the token where all API calls will be recorded.

    Otherwise this will return an instance of CVClient where API calls are mocked using previously recorded API messages.
    """
