What this PR does / why we need it:
When running canary with client side certificates (introduced in grafana#6310), a new
http.Transport
is being created for each request 🤦♂️. As a result, connections are left open until they timeout an hour later. This quickly causes resource exhaustion and errors likedial tcp 1.1.1.1:1111: connect: cannot assign requested address
.This change will reuse the same transport for all requests just like
http.DefaultClient
is reused when not using client certs.
