Fix "maybe_close_down" race-condition
If downstream connection pool crashed and recovered while some
upstream was alive holding it's DC ID, it may return downstream
taken from the old incarnation of pool to new one because it's
registered under the same name.
Fix is to hold pool's PID instead of name

Use standard process registration for dc pools instead of ETS
There was a race-condition, that caused crashes.
We could use gproc, but it feels a bit overkill for ~10-20 processes
