pegasus-kickstart: Remove dfp
pegasus-kickstart: Cleanup tests and scripts
pegasus-kickstart: Remove dead code
pegasus-kickstart: Fix try-parse & show-if compile
pegasus-kickstart: Rename test directory
pegasus-kickstart: Add per-pid I/O, memory and CPU usage

These changes add one or more <proc> elements inside all of the <*job>
elements. The new <proc> elements are only available on Linux systems
with kernels >2.5.60 that support ptrace with exit events. The new
<proc> element contains information about the peak memory usage of
each child process, the start and end times of the processes, the
number of characters and bytes read and written, the utime and stime,
and the pid and parent pid. This information can be used to compute
the resource usage of a job.
pegasus-kickstart: Bump schema version

This is related to the new <proc> element.
pegasus-kickstart: Change linux/proc to linux/procs

This is to avoid a name collision with the new proc
element.
