Can rosa create oidc-provider cmd honor the http_proxy or https_proxy env variable ?

Issue

• When creating an OIDC provider using "rosa create oidc-provider" on a host that need proxy to access the Internet, it's failed with the following error messages.

ERR: There was an error creating the OIDC provider: dial tcp xx.xx.xx.xx:443: connectex: A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond.

• Your host needs to use http_proxy and https_proxy environment variables to access to the Internet.
• When testing the Internet access using curl cmd, it's no problem.
