Handle parsing the OpenSSL expiry times ourselves, since the BusyBox and and BSD versions of the "date" command don't support parsing like the GNU version does. #195

Handle parsing the certificate expiration times from OpenSSL with Lua code for better cross-platform compatibility.
We were previously calling
date --dateto parse these times, but that--dateflag is only supported by the GNU version ofdate. The BusyBox version ofdate(under Alpine Linux) does not support this type of parsing, and neither does the BSD version. Given these differences across default versions of thedateutility, it seems better to handle this ourselves in a more explicit fashion.As noted in #195 (comment), this dependency on GNU date originally cropped up in the v0.12.0 release, but it may have failed silently. v0.13.0 made these failures nosier in the logs, so this became more obvious. It shouldn't have affected any functionality, other than renewals not being as optimized, due to the certificate expiration date not being stored.
