Felix Fontein 9a096dd146 Refactor module_utils/crypto.py (#27)
* Refactor module_utils/crypto.py: split up into multiple smaller modules

* Remove superfluous files.

* Fix sanity errors.

* Move CRL entry dumping code to module_utils.

* Move obj2txt usage from CRL modules to module_utils/crpyto/cryptography_crl.

* Move generic I/O functions to plugins/module_utils/io.py.

* Add helper method for retrieving serial number of certificate.

* Add compatibility code into __init__.py.

* Fix syntax error, and add ignore.txt entries for non-empty __init__.
