As discussed in #1326, we're not going to remove name_prefix for
compute_ssl_certificate, because it makes the common use case more
ergonomic by a good amount, and the only cost is it's harder to maintain
the autogenerated code, and we've decided the benefits outweigh the
costs in this circumstance.
Rename all ID fields to {resource_noun}_id instead of removing them
outright. This means people can still get at the info.
Leave project's id deleted. It has been marked as Removed for months.
I'm fine with cleaning it up before 1.0.0.
Also, update website docs.
