This PR adds a reusable webclient for kube-agent-updater consumption.
As described in RFD-184, the updaters should now obtain update instructions by hitting
/find
.The kube agent updater is a long-running updater and checks the proxy endpoint frequently. To avoid creating a new HTTP client every minute, this PR extracts a reusable web client, offering the same
Find()
,Ping()
, andGetMOTD()
functions than the webproxy package.Goal (internal): https://github.com/gravitational/cloud/issues/10289
