Tim Burke 212525118c Add a swift-reload command 
Previously, WSGI server systemd unit files might have used something like

   ExecReload=kill -USR1 $MAINPID

This was risky; in the related change, reloads were made safer, but
required more than one ExecReload line. Meanwhile, systemd docs
(https://www.freedesktop.org/software/systemd/man/systemd.service.html#ExecReload=)
say

> It is strongly recommended to set ExecReload= to a command that
> not only triggers a configuration reload of the daemon, but also
> synchronously waits for it to complete.

which *neither* set of ExecReloads would do.

Now, add a new swift-reload command which, given a pid,

   * validates that the PID seems to belong to a Swift WSGI server
     manager process,
   * checks that the config used by that PID is still valid,
   * signals the PID to perform a seamless reload, and
   * waits for the reload to complete by monitoring the PID's children.

As a result, WSGI server systemd unit files can now use something like

   ExecReload=swift-reload $MAINPID

to follow systemd recommendations.
