Builds on CentOS 6.4 fail due to dependencies not met for the new 'cryptography' python package. The ADLS commit states that the new packages are only required for ADLS and that ADLS on a dev environment is only supported from CentOS 6.7. This patch moves the compiled requirements for ADLS from compiled-requirements.txt to adls-requirements.txt and passing a compiler to the Pip environment while installing the ADLS requirements. Testing: Tested it on a machine that with TARGET_FILESYSTEM='adls' and also tested it on a CentOS 6.4 machine with the default configuration.

To install new packages: 1) Add your package to deps/requirements.txt, or deps/compiled-requirements.txt if the the package needs a C/C++ compiler to build . You should specify the version number using the "foo == x.y.z" notation so future upgrades can be done automatically. 2) Run deps/download_requirements, it will download the package to the deps dir. 3) Run the "impala-python" command, this should detect that requirements.txt changed and automatically rebuild the virtualenv. 4) Now in the python prompt, you should be able to import the new module. To upgrade a package: 1) Edit deps/requirement.txt to use the version you need. 2) Go to step 2 above.
