backpatch "Set application_name per-test in isolation and ecpg tests."

We started to backpatch test infrastructure improvements more aggressively to
make it easier to backpatch test. A proposed isolationtester improvement has a
dependency on b1907d688, backpatch b1907d688 to make it easier to subsequently
backpatch the new proposed isolationtester change.

Discussion: https://postgr.es/m/861977.1639421872@sss.pgh.pa.us
Backpatch: 10-12, the commit already is in 13-HEAD
