contint::website regroups apache + basic files

We have several websites hosted on gallium, move the definition from
manifests/misc/contint under the contint::website module class. That
will make it easier to handle.

The manifest pass puppet-lint

Some files (such as .html and .css) are left behind, they will
ultimately be moved to integration/htdocs.git so we no more have to pass
via ops to update the websites.
