Simplify argument parsing in remote_gahp. #4434
Fix authentication options in remote_gahp and bosco_ssh_start. #4434

If the user specifies non-default authentication options to the
remote_gahp, it needs to pass those along to bosco_ssh_start.
Dust off our schedd restart tests. Write one new one #4472
which only cares if the schedd restarts(basic), convert 3 other
with 4 files per test to single file tests using updated methods.
We have issues with reconnects so for windows I needed to have two tests
of and the reconnect test for everyone else.
These things were basically incorporated into the test  #4472
run files.
