Health checker blocks the shepherd if docker registry is inaccessible

[blazekadam]

It is possible that this issue is reproducible only from within a docker.

Most likely, it's this line

shepherd/shepherd/docker/registry.py

Line 16 in ede07cf

response = requests.get(config.url + "/v2/_catalog", auth=HTTPBasicAuth(config.username, config.password))

perhaps an explicit timeout would do the job

Nah, we'll switch over to the http client provided by aiohttp and ditch requests. Shame on me for forgetting to rewrite this...

[blazekadam]

Ah, good point.
