Source virtualenvwrapper in python module

# Sebastian Wiesner <lunaryorn@googlemail.com>
Added conda virtualenv support to python module. (#1505) * Added conda virtualenv support to python module * Added instructions for Python module options to README Thanks to @egpbos for the original feature and @ickc for fixing the merge conflicts.

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.

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.

Improve startup time by skipping pyenv rehash After profiling startup time, I found that "pyenv rehash" is by far the slowest piece. This change skips rehashing on init. See https://github.com/pyenv/pyenv/issues/784#issuecomment-404850327 Also pass the shell explicitly, as suggested in https://github.com/pyenv/pyenv/issues/784#issuecomment-404944318, which provides a modest improvement. In total, this improves startup time from 1s to 0.3s on my machine.

[python] Improve and document `virtualenvwrapper` initialization flow Changes: * Simplify zstyle name `skip-virtualenvwrapper-init` to `initialize` avoiding double negation in name * Always perform `eval (pyenv virtualenv-init -)` at initialization * Prefer `virtualenvwrapper_lazy` over `virtualenvwrapper` when available * Honor `VIRTUALENVWRAPPER_VIRTUALENV` if it is defined. * Document about `VIRTUALENVWRAPPER_PYTHON` and `VIRTUALENVWRAPPER_VIRTUALENV` (this would be particularly important in macOS after recent homebrew update) * Add additional documentation for `initialize` in _README.md_ and _zpreztorc_ * Add aliases `py2`, `py3` as shortcut for `python2`, `python3` respectively

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`.

[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.
