Cmd to set key value in all config files

[mozey]

Usually it's a good idea to have the same keys across config files. That makes it easier to diff the files. If the key doesn't apply to the env then use the empty value.

This cmd might be invoked like this

./config -all -key APP_FOO -value xxx

By default set value in all config files, pass in -env to update a specific file only This is a bad idea because it would require a file glob by default. Rather stick with -all as above

This will require changes to Main, Cmd and Process functions

The -all flag will set a key value for all config.*.json and sample.config.*.json files in APP_DIR.

To set only config.*.json maybe use this syntax...

configu -env * -key APP_FOO -value xxx

...or for sample files only

configu -env sample.* -key APP_FOO -value xxx

Note, currently updating a key value replaces the entire contents of a file. Config files should be small (kilobytes) in most cases, so that is not a problem?
