* drop WITH_PYTHON2 option
* print warning message if WITH_PYTHON3 is disabled
* drop MGR_PYTHON_VERSION option, as we don't support use different
python version for python binding and ceph-mgr embedded python
interpreter anymore. as before switching to python3-only build,
we can build python3 and python2 python bindings, and ceph-mgr
can use either of them. but after switching to python3-only
build, ceph-mgr has to use whatever python version used to
build python binding.
* move WITH_PYTHON3 option to $top_srcdir/CMakeLists.txt, as ceph-mgr
and python binding will share this option.
* hardware ${PYTHON_VERSION} to 3
* hardware ${Python${PYTHON_VERSION}_VERSION_MAJOR} to 3
* only build boost library with python3
* s/Python_EXECUTABLE/Python3_EXECUTABLE/
* update the build scripts and packagings accordingly
* rename all cython${PYTHON_VERSION}_* targets to cython_*
* update distutils_install_module() so it does not take python_version
parameter anymore.

use the ones shiped from the latest cmake. which
* enables us to find the recent python intepreter and development files,
* find intepreter and development in a single `find_pacakge()` command,
simpler this way and less error prone.
and to accomodate this change:
* all `PYTHON${PYTHON_VERSION}_*` variables are renamed to
`Python${PYTHON_VERSION}_*` if we use `find_package(Python2...)` or
`find_package(Python3...)` to find python2 or python3 instead of using
`find_package(Python...)`.
* use "2" explicitly when using python2, as `Python_*` variables are not
defined anymore
* when compiling python support of ceph-mgr, continue using `Python_*`
variables. because we find the python interpreter and development
files using `find_pacakge(Python...)` for ceph-mgr.

* fix CYTHON_ADD_MODULE() macro. because python_add_module() offered by
FindPythonLibs.cmake creates a target with name of ${name}, which conflicts
with existing targets like "rbd" or "rados". so we can not reuse the
name in ${name}.pyx. and instead, we should specify the target name
explicitly.
* add distutils_install_cython_module() function to build and install
cython modules.
* we can split build and install of cython module, but the install phase
always tries to build the module. so keep it this way. will look at it
later on.
* move the variables initializations into the Distutils.cmake module.
