Burrow can't connect to HTTPS in the notifier

Nobody has claimed this yet.

Has anyone tried setting up 'Notifier HTTP' to a HTTPS URL? I receive an error that says `"Post https://....: x509: certificate signed by unknown authority"`

I am using Burrow on a golang:alpine image. Tried updating my endpoint's certificate on the ca-certificates level and using the "headers" option to pass on the key for connecting to the HTTPS URL.

My config is as below -
[notifier.newrelic]
class-name="http"
interval=10
threshold=1
send-close=true
url-open="https://xyz.com/events"
url-close="https://xyz.com/events"
template-post="/default-http-post.tmpl"
extras={ eventType="burrow" }
timeout=5
keepalive=30
headers={ X-Insert-Key="key"}

Start by reproducing the HTTPS failure with the shown Notifier HTTP configuration on the golang:alpine image, checking how its certificate authorities are used. Compare the behavior with a trusted HTTPS endpoint and define done as the notifier successfully posting to HTTPS without the x509 unknown-authority error.
