profiling

The contrast is not very good
As you can see the contrast is not very good

Plus it's a good idea to have a look at every single color in the pal

While setting up Parca for prometheus' prombench, I had to configure all the profiling configs, because we use a prefix.

Since the prefix is common to all, it would be useful to be able to provide the prefix.

instead of:

    profiling_config:                                                      
      pprof_config:
       memory_total:        
               enabled: true         

There are many instances of INSTR_CREATE macro documentation saying things like this:

* \param dc  The void * dcontext used to allocate memory for the instr_t.

That should have a # to link up the instr_t type.
