Drop boost::posix_time

Per the coding standard, if we can support what we need to do with
std variants of something, we should prefer that.  This commit adds an
iso8160 to string method that supports any arbitrary
std::chrono::duration object, which allows doing the full range of all
of our integer types, and reduces the complexity (and presumably compile
times) not pulling in a complex library.

Despite the heavy templating, this only appears to add 108 bytes of
compressed binary size to bmcweb.  This is likely due to the decreased
complexity compared to the boost variant (that likely pulls in
boost::locale).  (Ie 3 template instantiations of the simple one take
about the same binary space as 1 complex instantiation).

Tested:
Unit tests pass (pretty good coverage here)
