Ability to set initial admin security token in Kong Mesh

Requesting the ability to proactively set/declare the initial Admin token used by Kong Mesh during deployment.

We'd like to set the admin token in an env var with something like KUMA_ADMIN_USER_TOKEN=secret instead of the current requirement to retrieve the generated token like so: curl http://localhost:5681/global-secrets/admin-user-token | jq -r .data | base64 -d
