Daniel Nephin ff26294d63 consul: fix data race in leader CA tests
Some global variables are patched to shorter values in these tests. But the goroutines that read
them can outlive the test because nothing waited for them to exit.

This commit adds a Wait() method to the routine manager, so that tests can wait for the goroutines
to exit. This prevents the data race because the 'reset to original value' can happen
after all other goroutines have stopped.
