Adding '-verbose' will print out the allocation information for the
deployment. This also changes the job run command so that it now blocks
until deployment is complete and adds timestamps to the output so that
it's more in line with the output of node drain.
This uses glint to print in place in running in a tty. Because glint
doesn't yet support cmd/powershell, Windows workflows use a different
library to print in place, which results in slightly different
formatting: 1) different margins, and 2) no spinner indicating
deployment in progress.
This PR switches the Nomad repository from using govendor to Go modules
for managing dependencies. Aspects of the Nomad workflow remain pretty
much the same. The usual Makefile targets should continue to work as
they always did. The API submodule simply defers to the parent Nomad
version on the repository, keeping the semantics of API versioning that
currently exists.
This drops the testings stdlib pkg from our dependencies. Saves a
whopping 46kb on our binary (was really hoping for more of a win there),
but also avoids potential ugliness with how testing sets flags.
