Parse requirements files for global pip flags. (bazel-contrib#456)
Parse requirements files for global pip flags, then add them to the extra_pip_args array. Pass a copy of each cleaned up line (comments and line-breaks removed) to each whl_library repo verbatim. Then link based requirements or requirement lines with requirement specific flags work. Due to the pip restriction on using requirement specific flags in requirements.txt files only, write each requirement line to a temp file before invoking pip in each whl_library repo. Fixes bazel-contrib#438 bazel-contrib#447
