We should modify waitForActive() in mcsadmin to look at DBRM::getSystemQueryReady()

fixed... moved the waitForActive() from postConfigure and mcsadmin to oam APIs. added check for DBRM::getSystemQueryReady().

how to test...

1. postConfigure install and make sure system goes active and good return back to user
2. mcsadmin restartsystem and startsystem and make sure system goes active and returns success back to user.

The new wait period of 10 seconds in a loop is excessive. The previous wait of 3 seconds in a loop is much less annoying to a user.

changing design to sleep for 3 seconds instead of 10 and print the dot to the screen every 9 seconds. this will keep the dots from rapping around on on startups, like multi-node systems.

Build tested: 1.1.4-1 source

regression tested binary installation, restart system, shutdown and start system on a 1um2pm stack.

Also tested concurrent queries right after system became available.
