Build C/C++ packages with toolchain GCC to avoid ABI compatibility
issues. This requires a multi-step bootstrapping process:
1. install basic non-C/C++ packages into the virtualenv
2. use Python 2.7 from the virtualenv to bootstrap the toolchain
3. use toolchain gcc to build C/C++ packages
4. build the kudu-python package with toolchain gcc and Cython
To avoid potentially pulling in cached versions of packages
built with a different compiler, this patch also disables pip's
caching. This should not have a significant effect on performance
since we've enabled ccache and cache downloaded packages in
infra/python/deps.
Improve bootstrapping time significantly by using ccache and by
parallelising the numpy build - the most expensive part of the
install process. On a system with a warmed-up ccache,
bootstrapping after deleting infra/python/env takes 1m16s. Previously
it could take over 5m.
Testing:
Tested manually on Ubuntu 16.04 to confirm that it fixes the ABI
problem mentioned in IMPALA-4593. Initially "import kudu" failed
in my dev environment. After deleting infra/python/env and
re-bootstrapping, "import kudu" succeeded.
Also ran the standard test suite on CentOS 6 and built Impala on
a range of platforms (CentOS 5,6,7; SLES 11,12; Debian 6,7;
Ubuntu12.04,14.04,16.04) to make sure nothing broke.

This adds a bootstrap script and a "impala-python" command to
$IMPALA_HOME/bin that automatically runs the bootstrap and redirects to
the virtualenv python. Existing python scripts will later be updated to
use the this new "impala-python" command.
The bootstrap script will build a virtualenv to ensure a minimum python
version (2.6) and a well known set of dependencies. The bootstrap script
can be run with python 2.4 but 2.6 must already be installed on the
system. The resulting virtualenv will use 2.6 at a minimum.
Only dependencies explicitly listed in requirements.txt will be
installed and available (no system packages will ever be used). No
packages will ever be downloaded when setting up the virtualenv. In the
future new dependencies can be added by editing the requirements.txt
file. Installation through requirements.txt is a standard pip feature.
When requirements.txt is updated, the next run of "impala-python" will
rebuild the virtualenv.
