Fix FTBFS and crm cluster health command
Hi,
I prepared a set of changes to fix the "crm cluster health" command, which has been broken for a while.
Note that some of the changes will no longer apply after we get a new crmsh release, due to the changes in https://github.com/ClusterLabs/crmsh/pull/883 which moves the script contents into the main python package.
The remaining changes were forwarded upstream on https://github.com/ClusterLabs/crmsh/pull/925 and https://github.com/ClusterLabs/crmsh/pull/926
This has been forwarded to Ubuntu at https://code.launchpad.net/~athos-ribeiro/ubuntu/+source/crmsh/+git/crmsh/+merge/414111
