Test-pmd already has a way to run a list of commands from file, but there
is no way to pause execution for a specified amount of time between two
commands. This may be necessary for simple automation, particularly for
waiting on some asynchronous operation such as link status update.

Add a simple sleep command to wait until certain number of seconds has
passed, using the newly added cmdline library floating point support.

Signed-off-by: Anatoly Burakov <anatoly.burakov@intel.com>

Notes:
    v1 -> v2:
    - Add floating point support to cmdline
    - Use floating point format for pause command
