Changed the configmap variable declarations to match proper language formatting.
Changed the configmap variable declarations to match proper language formatting.

Problem:
The configmap variables in appManager_test.go didn't match the recommended
GO language formatting.

Solution:
The configmap variables are now each defined as a var that is defined by
a function that reads the configmaps from separate files in
pkg/test/configs.
