RFE: API route to query servercheck data by host name or ID

[guzzijason]

Currently, this route is used to GET servercheck data:

/api/$version/servers/checks

This returns data for all servers. In order to better integrate with monitoring/alerting systems, I would like to have the option to request the same data for a specific host only, either by name or ID. Right now, its workable, but each individual monitoring check that uses this data would need to retrieve the large chunk of data and parse out the specific host the check cares about.

I can take this one since it is a duplicate of #5463
