feat(intelAMT): add support for HTTPS connections

[synthe102]

Description

This pull request add support for HTTPS connections with Intel AMT BMCs. Currently bmclib uses http as a default connection scheme which is not supported on modern AMT platforms (like the Minisforum MS-01 that I used to test this change), and there is no way to set the connection scheme to https with the current Machine API.

Why is this needed

This is needed to add support for AMT hosts that only support HTTPS connection scheme.

Fixes: #

How Has This Been Tested?

These changes were tested against a Minisforum MS-01 PC that only supports HTTPS AMT. A Machine was created that couldn't fetch the powerstate since the authentication would fail because the client would default to http. With these changes, rufio can successfully interact with the AMT BMC on the computer using https scheme.

How are existing users impacted? What migration steps/scripts do we need?

No migration is needed, the new hostScheme field defaults to http which keeps the default behavior.

Checklist:

I have:

• updated the documentation and/or roadmap (if required)
• added unit or e2e tests
• provided instructions on how to upgrade
