tests: All_protocol_startup sporadic failure

Browse Source 
the test_nexthop_groups function is failing occassionally
because the test executes 4 in succession sharp install
routes commands.  When I dumped the rib on a failed test
run there were only 2 of the 4 routes in the rib and
the two that were in were the last 2 installed.
The sharp daemon setups a event process where it
installs routes `automatically`.  If the previous
run is not finished entering a new command to install
the routes will mess up the last one from ever happening.
It is assumed that the user doesn't do stupid stuff here.
In this case I am just adding a small sleep between each
installation to just let the test proceed.
