Added `bricks auth login` and `bricks auth token` (#158)
# Auth challenge (happy path)
Simplified description of [PKCE](https://oauth.net/2/pkce/)
implementation:
```mermaid
sequenceDiagram
autonumber
actor User
User ->> CLI: type `bricks auth login HOST`
CLI ->>+ HOST: request OIDC endpoints
HOST ->>- CLI: auth & token endpoints
CLI ->> CLI: start embedded server to consume redirects (lock)
CLI -->>+ Auth Endpoint: open browser with RND1 + SHA256(RND2)
User ->>+ Auth Endpoint: Go through SSO
Auth Endpoint ->>- CLI: AUTH CODE + 'RND1 (redirect)
CLI ->>+ Token Endpoint: Exchange: AUTH CODE + RND2
Token Endpoint ->>- CLI: Access Token (JWT) + refresh + expiry
CLI ->> Token cache: Save Access Token (JWT) + refresh + expiry
CLI ->> User: success
```
# Token refresh (happy path)
```mermaid
sequenceDiagram
autonumber
actor User
User ->> CLI: type `bricks token HOST`
CLI ->> CLI: acquire lock (same local addr as redirect server)
CLI ->>+ Token cache: read token
critical token not expired
Token cache ->>- User: JWT (without refresh)
option token is expired
CLI ->>+ HOST: request OIDC endpoints
HOST ->>- CLI: auth & token endpoints
CLI ->>+ Token Endpoint: refresh token
Token Endpoint ->>- CLI: JWT (refreshed)
CLI ->> Token cache: save JWT (refreshed)
CLI ->> User: JWT (refreshed)
option no auth for host
CLI -X User: no auth configured
end
```
