> Create a KerberosHelper method to create the headless Kerberos identities and keytab files (inline). 
> This can be used to create the common identities and keytab files before parallel invocations attempt to do so. Due to a race condition, parallel invocations of the server-side actions to create principals and keytab files may lead to invalid keytab files being distributed to some host because the password contained in them were clobbered. 
> By calling this new method before calls to install and start services the potential of the race condition will be avoided. 
> {code}
> boolean createHeadlessKerberosIdentities(Cluster cluster, Map<String, Map<String, String>> existingConfigurations, Set<String> services)
> {code}
