e34e0ccd12 Check and update Agent's Management URL if is legacy (#406)
All the existing agents by default connect to port 33073 of the
Management service. This value is also stored in the local config.
All the agents won't switch to the new port 443
unless explicitly specified in the config.
We want the transition to be smooth for our users, therefore
this PR adds logic to check whether the old port 33073 can be
changed to 443 and updates the config automatically.

966661fe91 Serve Management gRPC and HTTP on a single 80/443 port (#400)
This PR is a part of an effort to use standard ports (443 or 80) that are usually allowed by default in most of the environments.

Right now Management Service runs the Let'sEncrypt manager on port 443, HTTP API server on port 33071,
and a gRPC server on port 33073. There are three separate listeners.
This PR combines these listeners into one.
With this change, the HTTP and gRPC server runs on either 443 with TLS or 80 without TLS
by default (no --port specified).
Let's Encrypt manager always runs on port 443 if enabled.
The backward compatibility server runs on port 33073 (with TLS or without).
HTTP port 33071 is obsolete and not used anymore.

Newly installed agents will connect to port 443 by default instead of port 33073 if not specified otherwise.

86a66c6202 Make Signal Service listen on a standard 443/80 port instead of 10000 (#396)
Right now Signal Service runs the Let'sEncrypt manager on port 80
and a gRPC server on port 10000. There are two separate listeners.
This PR combines these listeners into one with a cmux lib.
The gRPC server runs on either 443 with TLS or 80 without TLS.
Let's Encrypt manager always runs on port 80.

d4a3ee9d87 Load user profile when SSH (#380)
This PR fixes issues with the terminal when
running netbird ssh to a remote agent.
Every session looks up a user and loads its
profile. If no user is found, the connection is rejected.
