As discussed in WFLY-20611, we need to improve the user experience to create user credentials (application & management) for cloud deployment.

One of the approach is to use add-users.sh script to create these user credentials outside of the server directory and inject them to the deployment as a secret.

Currently, the add-user.sh script fails if the directories specified by -sc or -dc do not exist:

mkdir users-secret
./target/server/bin/add-user.sh -sc users-secret

What type of user do you wish to add?
 a) Management User (mgmt-users.properties)
 b) Application User (application-users.properties)
(a): a

 * Error *
WFLYDM0023: No mgmt-users.properties files found.

We could add an option to create the required properties file if they do not exist.
Something like:

-cf, --create-files  Create files & directories if they do not exist

With that enhancement, create a Kubernetes secret to hold the WildFly credentials would be:

./target/server/bin/add-user.sh -a -cf -u 'quickstartUser' -p 'quickstartPwd1!' -sc user-secrets
kubectl create secret generic users-secret --from-file=users-secret

This flag would be optional and disabled by default (to preserve the existing behaviour)
