Open GRPC socket before opening the DB and compactions

[matevz]

SUMMARY

When starting oasis-node, it takes some time to open Badger databases and run compactions. This is especially notable if you have ParaTimes configured. In the meantime, you have no idea what is the state of the node without checking the logs. I suggest we open internal.sock right after reading the config file. Then, during the DB compactions, running oasis net status would already return you meaningful status e.g. "Compacting database".
