Run as a command across a list of servers. A filter must be provided.  The filter can be a mix of instance ids and ec2 tags. This command can also take a path to a file. To specify a path to a file use file:// at the beginning of your file.

Examples:

    $ sonic command send hi-web-prod uptime
    $ sonic command send hi-web-prod,hi-worker-prod,hi-clock-prod uptime
    $ sonic command send i-030033c20c54bf149,i-030033c20c54bf150 uname -a
    $ sonic command send i-030033c20c54bf149 file://hello.sh

You cannot mix instance ids and tag names in the filter.
