[oe] pyOpenSSL in meta-oe

[Andreas Oberritter]

Since version 0.14, pyOpenSSL has an unfulfilled runtime dependency on
python-cryptographic (which in turn depends on python-cffi,
python-enum34, python-pycparser) and python-six, and is therefore
unusable in its current state.

I've just submitted recipes for all but python-cryptographic, because I
couldn't get the latter to work.

Upstream bugs:
https://github.com/pyca/pyopenssl/issues/157
https://github.com/pyca/cryptography/issues/1325

I guess it would be easier to switch back to 0.13 and fix the compile
error that appeared with openssl 1.0.2, unless somebody else steps
forward to write a working recipe for python-cryptographic.

Btw, how about moving python-pyopenssl to meta-python? There's only one
recipe depending on it, which should IMHO be moved as well (gateone).

Andreas
