HPCC-8677 Remove calls to setPasswordsFromSDS from ESP/EclWatch

When an ESP is started, memory leaks are reported due to multiple
calls to setPasswordsFromSDS(). And calling setPasswordsFromSDS()
is not a particularly secure mechanism. This fix remove the calls
from both ESP and EclWatch services.
