[FEAT] add tls to the receiver server

[edwinkys]

Feature Description

We want to have a server-side functionality that can be configured to run the receiver server with TLS. The certificates for the TLS should be provided by the user. This will contribute to an extra layer of security for this project.

Potential Solution

Tonic, the gRPC framework used in Phantasm, should allow us to add this functionality pretty easily.
