[Feature] Add support for admin login in SC

[YourTechBud]

Create a backend api for user to login into SpaceCloud.

API for login

API: Post : /sc/v1/login Payload:

{"username": "", "password": "<in clear text>"}

Response Payload

{"token": "<jwt token (hsa algo>"}

JWT Payload:

{"sub": "<username>", "exp": "<2hr>"}

We will consider changing password hashing in the near future.

API for Refreshing token (For the UI)

API: Post : /sc/v1/refresh-token Payload: NO Request Body

Response Payload

{"token": "<jwt token (hsa algo>"}

Assumptions:

• No api will be provided to create new users.
• Admin username and password will be provided as flags to sc
  • --admin.secret (ADMIN_SECRET)
  • --admin.username (ADMIN_USERNAME)
  • --admin.password (ADMIN_PASSWORD)

Create spacectl login command:

Attempts to login into SC to verify username and password and stores the same in a config file.

Behaiviour:

• Accept the following via. flags or survey:
  • --url
  • --username
  • --password
  • --password-stdin (to accept password via. std input)
• Attempt to login
  • Throw error on non 200
  • Store username and password in $HOME/.space-cloud/creds.json. Base64 encode username and password fields. This file will contain:
    • Username
    • Password
    • URL

Note: All spacectl command outputs should use this library: https://github.com/pterm/pterm
