reload_dshackle.sh: gate the reload on the 1:1 invariant

Browse Source 
Insert validate-dshackle-1to1.py between the overrides weave and the HUP signal:
a dshackle config routing >1 node for the same chain is REFUSED (exit 1) so the
live config stays active. Structural enforcement of 1 dshackle = 1 node/chain —
we can't attribute traffic to multiple nodes behind one proxy (no per-upstream
request metric; conn-seconds biases it). See /root/proxy-1to1-invariant-plan.md.
