Eliminate use of problematic url.Parse()

[cphvmware]

It doesn't work correctly with windows pathnames because they start with c: and the parser thinks that's a user name.

What this PR does / why we need it:
Without this change the windows driver won't start. The windows nodes get an error

invalid port :\csi\csi.sock after host

Testing done:
After the fix, windows Node Daemonsets Pods are no longer crashing. Test results (from PR #1996):

Special notes for your reviewer:

Release note:

Don't use url.Parse() on Windows unix:// sockets since it doesn't parse Windows filenames correctly.

Hi @cphvmware. Thanks for your PR.

I'm waiting for a kubernetes-sigs member to verify that this patch is reasonable to test. If it is, they should reply with /ok-to-test on its own line. Until that is done, I will not automatically test new commits in this PR, but the usual testing commands by org members will still work. Regular contributors should join the org to skip this step.

Once the patch is verified, the new status will be reflected by the ok-to-test label.

I understand the commands that are listed here.

Instructions for interacting with me using PR comments are available here. If you have questions or suggestions related to my behavior, please file an issue against the kubernetes/test-infra repository.
