The seqcli license only has the apply subcommand. For automation purposes it would be good if there would also be the option to check
for an already applied licence.

Like:

$ seqcli licence show
Serial: ...
Issued-By: ...
Licensed-To: ...
Subscription-Id: ...
...

$ seqcli licence show --json
{"Serial":"...", ...}

The api (GET api/licenses/license-server) and the nuget API library (https://github.com/datalust/seq-api/blob/dev/src/Seq.Api/ResourceGroups/LicensesResourceGroup.cs#L50) supports this operation, so this just seems to be a feature gap.

What are you thinking about this feature? I could make a PR if requested.

Thanks
