Source virtualenvwrapper in python module

python: Optimize completion for loading lazily on demand Move `pip` to separate completion definition delegating to pip to do all the completion work. Since the completion is loaded lazily on-demand, it avoids the performance overhead during Zsh initialization. Implementation note: The helper function `_pip_completion` implementation is based on the official pip completion function (which can be generated with `pip completion --zsh`) adhering to the newer compsys style. See: 'man zshcompsys' for more details.

Set `EXTENDED_GLOB` in the python module This is needed to find python. It is often already set because a user has the directory or completion module loaded before this, but that's not always true. See extensive debugging / further explanation here: https://github.com/sorin-ionescu/prezto/issues/1949 This does not fully resolve that issue, as there's another enhancement that I'll put up as a separate PR.

python: Update pyenv initialization flow per pyenv 2.0 In pyenv 2.0 onwards, it is not enough anymore to initialize pyenv in shell by just calling `pyenv init -`. We also need to update `path` to include pyenv shims by calling `pyenv init --path`. Also, honor `$PYENV_ROOT` if set but, no need to set it explicitly if not set. Instead, let the initialization script take care of that.

[python] Refine pyenv based virtualenv management Now that pyenv plugins availability is detected by directly probing 'pyenv', we need to rely on the same mechanism consistently. Further, we perform available pyenv plugin scan with native zsh techniques instead of relying on external commands.

python: Reformat and apply visual cleanup Changes: - Fallback to `virtualenvwrapper` without `pyenv` wrapper if `python` is available in path, regardless of whether `brew` is available. - Look up for availability of `python2` and `python3`, not just `python`. - Check for existence of path before adding to global `$path` array. - Adhere to more idiomatic Zsh operation and minimize redundant syntaxes. - Prefer looking up `$functions` for fully initialized `pyenv`.
