Update the doc link brought by the swift doc migration.
Although we had some effort to fix these before, it still left lots
of bad doc link, I separate these changes into 3 patches aim to fix
all of these, this is the 1st patch for doc/manpages.

The policy of giving projects vanity domains stopped about 5 years ago.
swift.openstack.org is a redirect to the canonical location -
docs.openstack.org/developer/swift. While we are not aiming to remove
the redirect any time in the forseeable future due to existing published
links pointing to it, we should at the very least stop adding more of
those links to the world.
