Delete cvd/metrics.

Most of the code under this directory is a subset of the following:

- Copied from host/commands/metrics
- Not being compiled
- Targeting the acloud metrics proto type rather than the Cuttlefish
  metrics proto type.

The only part being used is an informational notice on logging, which is
not the same as the latest notice we were approved to use.
