rndc-confgen: command not found

[Gavin Panella]

$ rndc-confgen
Command 'rndc-confgen' is available in '/usr/sbin/rndc-confgen'
The command could not be located because '/usr/sbin' is not included in
the PATH environment variable.
This is most likely caused by the lack of administrative privileges
associated with your user account.
rndc-confgen: command not found

I discovered this when running bin/test.rack in a new and up-to-date
16.04 container, running as the ubuntu user. I'm puzzled as to why the
ubuntu user should not have /usr/sbin in PATH given that ubuntu can sudo
to root, i.e. it obviously has /some/ privileges.

$ groups
ubuntu adm dialout cdrom floppy sudo audio dip video plugdev netdev lxd
$ echo $PATH
/usr/local/bin:/usr/bin:/bin:/usr/local/games:/usr/games:/snap/bin

A catch-all fix might be to refer to rndc-confgen by its full path when
MAAS calls it.

In ubuntu, non-root users do not have /usr/local/sbin, /usr/sbin, or /sbin in their path by default (though the user can override that.) Note that "sudo rndc-confgen" would work as well.

Assuming that it works in our case, then specifying the full path is the correct action.

I expect that this needs to be fixed for 2.0 because there is some path that would trigger it. If that's not the case, and it's only testing, then we can drop the 2.0 target.

The correct-and-trivial fix is to run it by its full path.
