🔖 Feature description

Basically something that can do this:

tools:
- name: eat
  type: api_call
  api_call:
    ...
    headers:
      Authorization: $ f"Bearer {secrets.EAT_API_KEY}"

Guidelines:

• [ ] secrets should be encrypted at rest with bcrypt or something (inside the db; check best practices)
• [ ] should only be available at "setup time" meaning not inside steps
• [ ] should be used as a convention for using inside sessions etc as well

Components

1. [ ] secrets table
2. [ ] api for CRUD
3. [ ] integration with task execution
4. [ ] integration with sessions
