> 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 ensureHeadlessIdentities(Cluster cluster, Map<String, Map<String, String>>
existingConfigurations, Set<String> services)
>       throws KerberosInvalidConfigurationException, AmbariException;
> {code}
