Changes

opentracing: Disable the fetch jaeger traces feature

With latest targets, the opentracing.ui module would not load because
javax.xml.bind comes from 2 dependency chains. So removing the
javax.ws.rs chain (the one necessary to fetch jaeger traces) fixes the
problem, until the javax.xml.bind package is upgraded in orbit.

callstack: Remove unnecessary reentrant lock in data provider

For large traces, all reading threads were waiting for the single build
thread to finish, which caused hundreds of blocked threads to be
spawned.

trace-event: Do not execute the analyses automatically

They should be triggered on demand, as rarely does one wish for all of
them and they take time and resources to build.
