Bundle Python version is outdated in OSGeo4w package

[JLiang]

Please consider upgrading Python to 2.7.10 or above in OSGeo4W

Current Python version in OSGeo4W is 2.7.5 (QGIS 2.18) However, TLSv1_2 wasn't added until Python 2.7.9.

For some API provider, like Github, they started to move to supporting TLS1.2, also requires that the Client's Hello Message carries with a server name indication (SNI), otherwise server end would reject.

Also it is likely that more and more web services will switch to TLS1.2, please consider upgrading the Python version (in the bundle package) at least to 2.7.10 or even higher.

In order to verify that, try in python console: import json, urllib2; print json.load(urllib2.urlopen('​​https://api.github.com/')) The situation is almost the same with Requests library.

It is not easy for Windows users workaround this SSL version problem, provided we continue using Python 2.7.5 in OSGeo4W.

Also, an additional problem with the old 2.7.5 version I've run into is that unit tests using the multiprocessing module may cause infinite process spawning on Windows. This should be fixed in Python 2.7.11+. (Python issue: ​https://bugs.python.org/issue10128)

I've also found that pip installs no longer work with python 2.7.5 because of the lack of TLS1.2 support.
