Auto wires in Brave tracing
Adds hooks for grip tracing in agent and server

…thin Genie server and agent

- Trace propagator to be able to put trace information from server to agent and extract it
- Tag adapter for modifying tags applied to spans that will allow inheritors to adapt tags based on need (e.g. internal netflix tag modifications)
- Trace cleanup class for synchronously flushing brave spans before agent shut down
- auto configuration to expose components as beans to be used

- Extract Trace information from environment at startup if possible otherwise a new trace will be instantiated
- close spans at agent termination
- Add annotations for agent state machine execution
- Add tag for the genie job id when pertinent
- Add tag for the agent command that is being executed

- Propagate trace information from agent launchers into environment variables for agent processes
- Annotate job launch process to show phases
- Tag job launch span with job id

Exported as GENIE_B3_TRACE_ID_HIGH, GENIE_B3_TRACE_ID_LOW, GENIE_B3_PARENT_SPAN_ID and GENIE_B3_SAMPLED environment variables
Can be used by downstream user job clients to continue to propagate the trace (e.g. to spark or presto, etc)
