Would it make sense to move useful functions/logic now in the tools into 
the external library, for example some functions now in crm_mon helping 
with parsing/displaying of cluster status? Eventually if the external 
library becomes very easy to be used and is simply exposed with 
python/go/whatever wrappers, any consumers would get the consistent 
functionality and even the current pacemaker CLIs would probably become 
thin wrappers as well.
