New quant login command

[stooit]

Is your feature request related to a problem? Please describe.
At present when running quant init commands a user needs to manually retrieve and provide project values.

This is inefficient and requires manual config retrieval via the UI/Dashboard.

Describe the solution you'd like
A user can authenticate with a new quant login command and an auth token is generated and stored locally. From this point on project config values can be pulled on demand, for example

quant init
*** Select a project **
  > project-a
     project-b
     project-c
  
     New project

As per the above this also allows project creation on demand too, rather than the back and forth required via the UI at present.

This would be great!
