Quota should not be hard-coded #18
Description
Quota exists in the system in rescue-api as well as rescue-proxy.
For rescue-api it is defined here:
rescue-api/services/credentials.go
Lines 31 to 57 in 4562a95
(ignore L43)
rescue-api will not issue new credentials when there are already count credentials issued to a node in the last window duration.
authValidityWindow is enforced by rescue-proxy, but important for rescue-api to have knowledge of.
As new entities want to run rescue node instances, they may wish to have separate quotas configured. Instead of hard-coding these values, they should be passed at runtime. If not passed, the current values should be used as defaults.
In terms of passing them at runtime, either a yaml file or structured cli args should suffice. Currently there are only 2 operator types, so cli flags aren't too cumbersome, but if we ever add a third it will be a lot, so perhaps a yml file is better.
