Allow user to specify output of node name/ID format globally instead of in each command

Request
Support a variable in the cluster configuration via mmchconfig that allows a user to specify if node name output in any command should be done via
1. Explicit shortname even if it includes duplicates
2. Shortest unique name possible
3. FQDN
4. Only specify node ID integer value
Without having to specify it via command arguments in every command they run

Currently between the commands of mmgetstate and mmlsmgr, the commands use different underlying code to determine and output a short version of the host name. Depending on the cluster configuration and names of nodes this may or may not be the same output between commands. Some commands (not not all) support using -fqdn to get a fqdn output for commands but this requires using the -fqdn option in all commands and as all commands don't support it... frustration comes. Also, currently most commands do not offer the option of outputting the node ID instead of a node name. Node ID's are inherently unique short length integers that never change over time for the duration of the existence of any node (and are not re-used).
