Fix traceback with using GCE on EL6 with python-crypto2.6

updated intro to new become syntax, also added link to full become docs

This fix resolves an issue on EL6 systems where there may be multiple versions
of pycrypto installed.  EPEL provides both `python-crypto` and
`python-crypto2.6`.  These packages are co-installable.  However, modules
importing the `Crypto` library must specify which version to use, otherwise the
default will be used.

This change follows the same pattern established in `bin/ansible` for
specifying python library requirements.

Fixes #10736
