fix(conductor): enable tls for grpc connections (#925)

## Summary
Added a couple of tonic features to conductor so it can use tls and
http2 correctly.

## Background
When connecting over an https http2 (h2) connection conductor would get
errors stating `http2 error: connection error detected: frame with
invalid size, connection error detected: frame with invalid size`. Tonic
wasn't using tls because it wasn't turned on. Adding these two features
allows "native" certs for client to be used by default and uses tls and
http2 correctly when making client requests.

## Changes
- enabled `tls` and `tls-roots` features on tonic in conductor 

## Testing
Ran conductor locally against dusk-4 network. Additionally ran local
smoke test using the newly built image which confirmed still works over
non https urls.
