Adding shell commands for manipulating content via content providers.

1. This change adds the shell command to the bin folder on the device.
   This will enable using shell commands (assuming right permissions
   are held) on a user build to manipulate state of content providers.
   For example, this will be used for running CTS tests that rely on
   secure settings without adding intermediary APKs and/or manual setup.
