Upgrade to prometheus/common 0.62.0 with breaking change (#1712)

common 0.62.0 switches NameValidationScheme global variable to UTF8Validation.
While relaxing validation this will likely yield test failures downstream.

It's unfortunate, but the alternatives were worse: prometheus/common#724

Good news is that client_golang should work with older common deps and callers can
easily change model.NameValidationScheme value to old value to solve any compatibility issues.
