xonsh-click-tabcomplete uses pip internal API ... and it's gone now

[Achimh3011]

Hi,
with Version 10 pip has removed internal APIs from export (as previously announced).

Starting xonsh with xonsh-click-tabcomplete and a current pip (≥10.0) now yields

pip removed `get_installed_distributions`

Workaround is downgrade to 9.0.3:

xpip install pip==9.0.3

(but it comes back after each upgrade of course...)

Happens to other packages as well:

• AttributeError: 'module' has no attribute 'get_installed_distributions' Miserlou/Zappa#1471
• get_installed_distribution has gone from module pip pypa/pip#5154

(Accidentally filed xonsh/xonsh#2637 for the problem, closed it now)

Is this issue creating this DepWarning when loading click_tabcomplete ?

$ xonsh                                                                              (base)
<unknown>:1: DeprecationWarning: invalid escape sequence \w
xonsh: For full traceback set: $XONSH_SHOW_TRACEBACK = True

Yes, that's the one.
