Implement a quickstart command for minder

[rdimitrov]

The following PR implements a quickstart command which is intended to provide a happy path to getting started with minder and be executed after a user has authenticated and enrolled their provider.

Covers the following functionality:

• Prompts the user to enroll their repository provider
• Prompts the user to register one or more repositories with Minder
• Prompts the user to create a secret_scanning rule type
• Prompts the user to create a profile called quickstart-profile with the secret_scanning rule type set to enabled for their registered repositories.

Screenshots:

• Step 0 - Welcome

* Step 1 - Provider enrollment * Step 2 - Repository registration * Step 3 - Prompt for confirming the creation of secret scanning rule type * Step 4 - Prompt for confirming the creation of a profile using that rule type and the list of repos it will be applied to * Step 5 - Confirmation of the created profile

Fixes #1652
