In documentation, make sure every CLI command specify location explicitly

This is followup on JBEAP-13441. Does not rely on default location. Make sure every CLI command in documentation specify location explicitly. This make it easier to remove "if location is not set in CLI, default credential-store name is used as location"

I have searched in [1] - [5] , I have found one such example in [1]

• 4.1.12. Using Credential Stores in a Managed Domain

  /host=master/server=server-one/subsystem=elytron/credential-store=test:add(relative-to=jboss.server.data.dir,credential-reference={clear-text="secret2"},create=false)
