[receiver/vcenter] Switches Over Metadata Configs Waiting for v0.100.…

…0 Release (open-telemetry#32913)

**Description:** <Describe what has changed.>
A number of configurations were disabled by default and had warnings
that they were going to be enabled in v0.101.0 (1 metric had a warning
that it was going to be removed).

Now that v0.100.0 has been release, I have removed all of these
warnings, and made the modifications that the warnings "warned" about. I
have also updated the tests to reflect this.

**Link to tracking Issue:** <Issue number if applicable>
open-telemetry#32803 open-telemetry#32805 open-telemetry#32821 open-telemetry#32531 open-telemetry#32557

**Testing:** <Describe what testing was performed and which tests were
added.>
Unit/integration tests updated and tested. Local environment tested.

**Documentation:** <Describe the documentation added.>
New documentation generated based on the metadata.
