[v2] fix(contrib/hashicorp/{consul,vault}): pin armon/go-metrics to v0.4.1

[darccio]

What does this PR do?

Pins armon/go-metrics to v0.4.1 using a replace directive.

Motivation

To reduce CI times and noise in smoke tests' logs, we pin github.com/armon/go-metrics to v0.4.1, the last version released before it was migirated to Hashicorp's organization.

Without this, running our smoke tests that rely on go get -u tend to run longer due to Go's toolchain mechanism to try to find the right version that fits the import URL. Versions higher than v0.4.1 use github.com/hashicorp/go-metrics instead.
