This class was previously using a cached_attr for its 'localhost' attribute,
representing the Puppet::SSL::Host entry corresponding to the cert in
Puppet[:certname]. We now no longer expire this attribute. This has the effect
that a change to certname during the lifetime of an agent will not be reflected
in the certificate it uses. If this behavior is desired, it will need to be
reimplemented another way.

Keep alive has been disabled since 2008, and seems to have caused problems when
it was enabled before then. Since there doesn't seem to be any push to get it
working again, just remove it to simplify this code.

This also allows us to entirely remove the usage of Puppet::Util::Cacher from
HttpPool.

Doing a require to a relative path can cause files to be required more
than once when they're required from different relative paths.  If you
expand the path fully, this won't happen.  Ruby 1.9 also requires that
you use expand_path when doing these requires.
