[overlord-issues] [JBoss JIRA] (SRAMP-562) Convert S-RAMP UI errai services to jax-rs endpoints

Convert S-RAMP UI errai services to jax-rs endpoints ---------------------------------------------------- Key: SRAMP-562 URL: https://issues.jboss.org/browse/SRAMP-562 Project: S-RAMP Issue Type: Task Components: UI Reporter: Eric Wittmann Assignee: Brett Meyer Currently we use Errai RPC services to communicate between the UI client and the server. We should switch all of these from Errai RPC to REST, which would allow us to remove all server-side Errai dependencies and thus no longer use CDI. This is a big win when running in Fuse and it doesn't make the UI any more complicated. It also has the side effect of introducing a REST API for the user interface, potentially allowing alternative implementations, integrations, embedded components in other UIs, etc.
