What’s the problem you're trying to solve

Support Canner Enterprise's PAT Authentication method

Describe the solution you’d like

Add a extension authenticator "CannerPATAuthenticator" to restrict only users of Canner Enterprise could access VulcanSQL API

YAML example:

extensions:
  authenticator-canner: @vulcan/module_path

auth:
  enabled: true

authenticator-canner:
  options:
    canner-pat:
        host: string
        port: number
        ssl: boolean

The CannerPATAuthenticator will recognize whether a token is a PAT token with the prefix "Canner-PAT"(case-insensitive) in the authorization header / payload / query string
eg:

Authorization: "Canner-PAT your_canner_pat_token"
