fix(mirror): initialize meter to prevent panic (#9712)

# Which Problems Are Solved

With the change of #9561, the `mirror` command panics as there's no
metrics provider configured.

# How the Problems Are Solved

Correctly initialize the provider (no-op by default) for the mirror
command.

# Additional Changes

None

# Additional Context

relates to #9561 -> needs backports to 2.66.x - 2.71.x and 3.0.0-rc
