[Stack Monitoring][Angular removal] Add error handling to requests

[estermv]

Add error handling to stack monitoring requests.

Technical notes

In Angular we are using this error handler to show some toast when there is an error in a request.
Since we still have the Legacy class in react, it could be easily migrated just replacing history with the useHistory hook.
It's also using a formatMsg function from kibana_legacy that we would need to check if we can still use.
