Long: `Deploy (prepare and activate) an application package.
When this returns successfully the application package has been validated
and activated on config servers. The process of applying it on individual nodes
has started but may not have completed.
If application directory is not specified, it defaults to working directory.
When deploying to Vespa Cloud the system can be overridden by setting the
environment variable VESPA_CLI_CLOUD_SYSTEM. This is intended for internal use
only.
In Vespa Cloud you may override the Vespa runtime version for your deployment.
This option should only be used if you have a reason for using a specific
version. By default Vespa Cloud chooses a suitable version for you.

Example: `$ vespa deploy .
$ vespa deploy -t cloud
$ vespa deploy -t cloud -z dev.aws-us-east-1c # -z can be omitted here as this zone is the default
