[yocto] [PATCH] git-pw: include bundle sub-command

[leonardo.sandoval.gonzalez at linux.intel.com]

From: Leonardo Sandoval <leonardo.sandoval.gonzalez at linux.intel.com>

This new command allows to fetch bundles (set of selected patches by the user)
and print them into the stdout. For the moment, bundles must be public (otherwise
these wont be found)

Command line example:

openembedded-core$ git pw bundle newbundle --username lsandov1
