Add new Services tab to accounts, allow scaling up and down different services #16
Description
Why:
We wanted to be able to scale up the worker-gj service to spin up a few new processes to help with a batch import. It would be handy if we could do this from the rack gateway UI.
Implement:
New "Services" tab, with a table e.g.:
| Service | Processes | Scale |
|---|---|---|
| web | 3 | 3 ✏️ |
| worker | 3 | 3 ✏️ |
| worker-gj | 1 | 1 ✏️ |
E.g. Click the edit icon and the number turns into:
| Service | Processes | Scale |
|---|---|---|
| web | 3 | [ 3 ] 💾 |
At the same time it could be handy to have a 🟥 stop button on every "Processes" row, so we can manually stop processes too.
