Enhance client-side gRPC TLS configuration

[cescoffier]

Previously, utilizing JKS or P12 keystores and truststores in gRPC clients was restricted due to limitations inherent in legacy gRPC-Java-based clients. However, this commit expands upon the existing configuration by introducing support for JKS and P12 in the Quarkus (Vert.x based) gRPC client.

This commit also extends the tests for both clients and servers using various certificate formats and configuration (like mTLS)

@geoand we can follow the same model for the rest client (until I introduce the registry)

[geoand]

Cool, I'll resume me PR based on this work

[geoand]

Actually I am going to wait for the big rename to be merged so we don't mess things up
