[Geneva.Metrics] Add option to disable name validation

[CodeBlanch]

[Note: This requires an OTel SDK with 4187]

Changes

• Adds DisableMetricNameValidation connection string flag which will set the validation regex to .*

Considerations

• We could expose a regex but my concern there is the SDK might move to some other mechanism in the future. I thought a simpler blanket disable option might get the job done without locking us into anything which might be hard to support long term.
