Hip interval to metababel

[DonAurelio]

• Migrate hip interval to metababel.
• Update the hip_model generation script to include common_context, package_context, and environment. Since the script babeltrace_to_metababel_model require those fields to be defined.
• Create a new babeltrace_to_metababel_model script to parse the old model to the metababel version.
• Delete clock_snapshot_value keyword from the xprof/interval_model.yaml. Since the interval events do not have a clock.

Stil working on the Makefile, distcheck still not working :(

Haha, got beaten by that many time :) We can have a look together on Monday. Look like you forgot add

I think, the CI doesn't pass because the gemm have not updated.

I think we are goo now.

We can void the $(srcdir) in the dependencies since btx_interval_model.yaml and btx_timeline_params.yaml are in EXTRA_DIST, that's why it works before. This tells Make that those dependencies exist and we need to copy them for distribution (only when make dist is issued, not during build).

Then, it is mandatory to place $(srcdir) in the command since those files won't be present in the build dir when we issue make. I chose to keep $(srcdir) in the dependencies to tell this dependencies are not in the build directory at build time (make). What do you think?

$(BTX_TIMELINE_GENERATED) &: $(srcdir)/btx_interval_model.yaml $(srcdir)/btx_timeline_params.yaml
    $(METABABEL) -u $(srcdir)/btx_interval_model.yaml -t SINK -o btx_sink_timeline -p btx_timeline -c timeline --params $(srcdir)/btx_timeline_params.yaml

Good enough, it was not the main of this PR :) I just merged it, so we can move forward :)
