#2628 tools/amf: improve error checking and naming convention

[Gary Lee]

amfclusterstatus expects the node ID in hex format. It should be consistent and prefix the node ID with 0x, in its output.

root@SC-1:~# amfclusterstatus -c 0x2010f
2010f is a Controller node

root@SC-1:~# amfclusterstatus -c 2010f
7da is not a Controller node

This is preferred:

root@SC-1:~# amfclusterstatus -u 0x2010f
0x2010f is up

In addition, invalid input prints:

root@SC-1:~# amfclusterstatus -u abc
0 is not up

Conflicting options are allowed:

root@SC-1:~# amfclusterstatus -u -c -s
At least one controller is up

amf: improve error checking and display [#2628]

* nodes are prefixed with '0x', eg '0x2010f' instead of '2010f' to match input
* options 's', 'c', 'u' are incompatible and are rejected when used together
