Use: "api-key",
Short: "Create a new developer key for headless authentication with Vespa Cloud control plane",
Long: `Create a new developer key for headless authentication with Vespa Cloud control plane
A developer key is intended for headless communication with the Vespa Cloud
control plane. For example when deploying from a continuous integration system.
The developer key will be stored in the Vespa CLI home directory
(see 'vespa help config'). Other commands will then automatically load the developer
key as necessary.
It's possible to override the developer key used through environment variables. This
can be useful in continuous integration systems.
Example of setting the key in-line:
export VESPA_CLI_API_KEY="my api key"
Example of loading the key from a custom path:
export VESPA_CLI_API_KEY_FILE=/path/to/api-key
Note that when overriding the developer key through environment variables,
that key will always be used. It's not possible to specify a tenant-specific
key through the environment.
