Implement ethical metrics migration

[pablomendezroyo]

Implement ethical metrics migration: ethical metrics will switch from using package ethical metrics to use new core package TOR:

• Service API will no longer be needed, requests from the ethical metrics daemon will go directly from dappmanager to ethical infra using tor core package socks
• Prometheus service will no longer needed since it will expose the Prometheus from DMS
• Tor service will be replaced by the new tor core package

The migration will consist of the following:

1. Install new core
2. New dappmanager starts
3. Dappmanager realizes that ethical metrics legacy is running
4. Dappmanager fetches tor instance from legacy ethical metrics using /instance endpoint
5. Send unregister with dontSendUnregisterNotification https://github.com/dappnode/monitor-proxy/blob/a26edf0b77ba42ea5f54816c1822e97470fd15ad/src/apis/server/register/types.ts#L7. This will be using the socks from tor ethical metrics pkg
6. Installs new tor core package
7. Sends "register" request to proxy with dontSendWelcomeNotification https://github.com/dappnode/monitor-proxy/blob/a26edf0b77ba42ea5f54816c1822e97470fd15ad/src/apis/server/register/types.ts#L15. This will be using the socks from tor core package
8. Removes legacy ethical metrics

This will entail data historic lost
