Do node checks in parallel

Browse Source 
The checking of MariaDB and Galera nodes is now done asynchronously while
the MaxScale check is done which leads to faster testing. Rough
measurements show that doing all the work in parallel reduces test startup
time by two seconds. Most of the time appears to still be in the MaxScale
startup which takes on average three to four seconds per test.
