Error handling: lagoon_api_token, lagoon_api_endpoint for plugins/modules

[steveworley]

lagoon_api_token and lagoon_api_endpoint are required parameters to all API requests and if not provided the play fails with an unhelpful message TypeError: a bytes-like object is required, not 'str'. We should make sure that these are handled properly and a usable error message is provided.

We should look to try and do the following:

• Set a default value for lagoon_api_endpoint
• Attempt to generate a token with host configuration - lagoon will respond with a token via SSH

ssh -oStrictHostKeyChecking=no [email protected] -p 32222 token
