how to add a new backend , like openfaas

@tanwww The easiest way is to copy-paste a backend from https://github.com/lithops-cloud/lithops/tree/master/lithops/serverless/backends. For example, you can copy the ibm_cf backend, rename it to openfaas, and then change the implementation of all the internal public methods. (you can delete all the private methods and create new ones if necessary)

As with the other backends, A new backend must have (at least) 3 files:

• the entry_point.py: This file will go in the runtime to handle the incoming requests and run the functions.
• the config.py: Used to verify the user-provided config variables, and fill those that can be defaulted.
• and (in your case) the openfaas.py: Contains the logic to invoke the functions, and to create/build/delete the runtime
