documentation: simplify running make check

Encapsulate the compilation steps (install dependencies, autogen.sh,
configure, make check) in the run-make-check.sh script. Update the
developer documentation to point to this script instead of multiple
steps.

It is intended as a tool to help new developer make sure their patch is
sane, it focuses on efficiency (runs make check in parallel if possible)
and coverage (enables docker based tests if possible).

 Development

-After installing the dependencies described in the ``README``,
-prepare the git source tree by updating the submodules
+The ``run-make-check.sh`` script will install Ceph dependencies,
+compiles everything in debug mode and runs a number of tests to verify
+the result behaves as expected.
 
 .. code::
 
-	git submodule update --init

-To build the server daemons, and FUSE client, execute the following:

-	./do_autogen.sh -d 1
-	make -j [number of cpus]
