Service status board

[kristianharju]

Adds a service status dashboard for authenticated users, where the user can see the current availability of MeteoGate services.

• The backend runs a simple HTTP status check for each configured service and retries up to three times. The delay between retries increases exponentially (e.g., 2, 4, 8 seconds), giving the service more time to recover
• The UI refreshes the status dashboard every 30 seconds
• The backend caches the status response for 30 seconds by default
• All settings can be configured, see https://github.com/EUMETNET/Dev-portal/blob/service-status-board/backend/config.default.yaml and https://github.com/EUMETNET/Dev-portal/blob/service-status-board/Helm/dev-portal/values.yaml
• Also pins the Vault version to 1.21.1 since the latest version 2.x.x does not work without some changes

One slight thing I noticed, is that when you access the status page after getting an API key and go back to the developer portal, the api key disappears. A minor thing, but can be frustrating for users.

How to reproduce:

1. login to developer portal
2. Get API key
3. Go to status dashboard
4. Go back to developer portal

Yes, it is the same when you click "Get API Key" and then refresh the page.

How about if:

1. Login to developer portal
2. Select "Show Routes"
3. Go to "MeteoGate Status Dashboard"
4. Then select "<- Back to Developer Portal"
5. You get back to Routes view

and

1. Login to developer portal
2. Select "Get API key"
3. Go to "MeteoGate Status Dashboard"
4. Then select "<- Back to Developer Portal"
5. You get back to API key view

and

1. Login to developer portal
2. Select "Delete API key"
3. You get notification "API key deleted successfully!" and "Your API key has been deleted."
4. Go to "MeteoGate Status Dashboard"
5. Then select "<- Back to Developer Portal"
6. You get back to view that displays "Click a button above to get started" (not the "Your API key has been deleted.")
