Infisical support UNIX socket bindings

[jenova-marie]

The cloud I'm building is mTLS via SPIFFE/SPIRE using Envoy mTLS proxy on each instance to expose containers. Envoy (and Caddy) can easily proxy to unix sockets. My preference for unix sockets over TCP/IP is for the obvious reason - no tcp/ip stack involvement - and the additional security I can place on the unix socket itself.

For incoming connections it would be really sweet to Envoy proxy directly to Infisical via unix socket.

In my particular case - during the dev period of only my cloud activity - I have postgresql, redis, and infisical running on the same instance. I would like the ability for Infisical to use unix socket connections to both pg and redis - however specifying the correct pg connection string - it still appears Infisical attempts to connect to 127.0.0.1:5432. I didn't test redis and just turned back on the tcp/ip stack for all services.

Thank you for a truly great product!
