Describe the problem that is addressed by this PR
When PR #28563 upgraded
http-proxy-agent
it didn't properly pass alongport
as this is now encoded in the proxy URL instead of the agent options.This PR trims down the unnecessary parsing we are doing to turn the proxy URL into
ProxySettings
, preferring to pass the URL as-is tohttp-proxy-agent
and avoid losing information. In cases where we receiveProxySettings
we will convert it into a URL correctly.For unknown historical reasons,
getDefaultProxySettings
was exposed as public surface, but since we no longer need this internally, I have marked it as deprecated so we may remove it in a later major version.Are there test cases added in this PR? (If not, why?)
Existing tests were updated to validate the proxy URL being set correctly on the agent itself.
