The current CLI application includes a command set that is confusing with respect to the current API methods. For example, the API defines a MNRead.get() operation, which is accessed in the CLI using the 'data' command, even though it sometimes will return data and others will return metadata. Also, the CLI includes a command named 'get' which doesn't invoke the similarly named API method, but instead displays a list of parameters set in the CLI. We should refactor the CLI to have the command set correspond to the names of the API methods, so that the correspondence is clear. IN particular, the CLI command 'get' should execute MNRead.get(). Others need to be reviewed for consistency. I suggest renaming the current CLI command 'get' to 'show', which is typically used in clients to show configuration settings.

By using the full method name from the API, the correspondence between CLI & API will be clear. We can then later allow unambiguous abbreviations of commands (see #2374), which will allow people to shorten commands.
