cmd/satellite: Allow core & API without live accounting cache

Browse Source 
Allow the satellite commands which uses the live accounting cache (core
and API) to run when at the time that its instantiated there is an error
connecting to the backend.

This prevent that if live accounting backend is down we can run these
services because:

1. The services must run despite of the cache backend being down
   although it may be degraded.
2. We may need to start new replicas of the services or the services in
   a different place while we are troubleshooting and fixing the cache
   backend system.
3. Our services may restart when the cache backend or the network
   connecting to it fails momentarily.
