> Allow all nodetool commands which print out the state of the node or cluster to do so in a way that makes it easy to re-use or paste on other nodes or config files.
> For example, the command getcompactionthroughput formats its output like this:
> {noformat}
> [jshook@cass4 bin]$ ./nodetool getcompactionthroughput      
> Current compaction throughput: 64 MB/s
> {noformat}
> But with an --as-yaml option, it could do this instead:
> {noformat}
> [jshook@cass4 bin]$ ./nodetool getcompactionthroughput --as-yaml
> compaction_throughput_mb_per_sec: 64{noformat}
> and with an --as-cli option, it could do this:
> {noformat}
> [jshook@cass4 bin]$ ./nodetool getcompactionthroughput --as-cli
> ./nodetool setcompactionthroughput 64{noformat}
> Any other nodetool standard options should simply be carried along to the --as-cli form, with the exception of -pw.
> Any -pw options should be elided with a warning in comments, but -pwf options should be allowed. This would allow users using -pw to append a password at their discretion, but would allow -pwf to work as usual.
> In the absence of either of the options above (--as-yaml or --as-cli) the formatting should not be changed to avoid breaking extant tool integrations.
