Improve/align Windows credentials mapping between registry, facts, docs, and credential storage

[sgnn7]

Is your feature request related to a problem? Please describe.

Currently we don't have a standardized way to talk about how the appliance url matches to the windows credential storage in a meaningful way. This issue is concerned with unifying it all in a single and consistent pattern (currently <host>:<port>).

Describe the solution you would like

The chosen approach would update these items:

• Docs
• HFT identity creation (if needed)
• WinCred matching
• Possibly other things (TBD)

Describe alternatives you have considered

This issue seems irrelevant with v3 at this time as we do not have multiple ways of setting WinCred credentials. Closing.
