PYRO-87: Mock Client

[sargon64]

Mock client for emulating the petro pannel todo:

• add a gui
• find out what the endpoints actually do
• ???
• profit

We're gonna need the mock client to request to the following alerion endpoints:

• GET /api/servers/:uuid
• DELETE /api/servers/:uuid
• GET /api/servers/:uuid/logs
• POST /api/servers/:uuid/power
• POST /api/servers/:uuid/commands
• POST /api/servers/:uuid/install
• POST /api/servers/:uuid/reinstall
• POST /api/servers/:uuid/ws

Plus, an interface to interact with the full websocket API.

IMO, mock_client should be a library for interacting with alerion, pretending you're a panel. It can then be used for real scenario benchmarking/testing, security testing, etc. We can then implement alerion_benchmark, alerion_ui_client, etc.

Few concerns for now:

• Why are there merge conflicts in alerion_core? This shouldn't touch anything in core alerion.
• Most serde-related structs are going to be shared between core and mock and should be in alerion_datamodel. Please move those in alerion_datamodel; we can then integrate core with datamodel in a later PR.
