This patch adds the option to specify URLs to advertise for clients and peers.
This will facilitate etcd communication through nat, where we want to listen
on a local IP, but expose a public IP to clients/peers.
This is an example of a race-free long-poll server and client. It uses a
redirection method to signal that the "Watch" is running.
Other race-free methods exist.
This patch adds autoedges between users and groups, and extends
users with additional fields for supplementary groups and a named
primary group. Also, some small fixes to log and error messages.
This would previously panic since it wouldn't get a kind, and the meta
parameters would overwrite the defaults so it would block because limit
didn't have the default of +inf.
The removal of the SetKind was my fault in:

It's funny because it ends in `bad`. Guess I should have checked that!
Note: When go-grpc-prometheus was in the main $gopath (even at this
version) and everyone else was where they always were in vendor/ this
didn't build! It gave errors like:
have SendHeader("github.com/purpleidea/mgmt/vendor/google.golang.org/grpc/metadata".MD) error
want SendHeader("google.golang.org/grpc/metadata".MD) error
and I got frustrated. Putting it "next" to the other vendored deps seems
to have fixed this. Where are the golang docs that explain this
phenomenon?
This also requires golang 1.8+ as that is a requirement for etcd. It's
probably a reasonable thing for us too.
Note the older versions of etcd had some bugs with the concurrency
package and other things, so this is a necessary bump.
This adds validation that ensures that Msg Priority field is one of the following values:
"Emerg", "Alert", "Crit", "Err", "Warning", "Notice", "Info", "Debug".
Previously, there was an extremely rare race where we would startup,
kick off the Run method in a goroutine, and then run Exit before Run got
very far in its execution. If Run ran some early sections of its code
_after_ we had Exited, we would trigger a panic due to the converger UID
being unregistered.
This patch blocks Exit from progressing until Run has started and
finished running. It also adds a Ready method so that you can monitor
this signal yourself if you'd like to add the necessary wait to your
code.
Graph changes from autogrouped -> not autogrouped or vice versa cause a
panic (or I assume a leak) because we compared the auto grouped graph to
the ungrouped one, which would cause an Exit on an unstarted Vertex.
This includes a test that seems to reliably reproduces the issue.
