Update Gearcmd to v0.10.0 -- defaults pass-sigterm to true
Update Gearcmd to v0.10.0 -- defaults pass-sigterm to true

Context: https://github.com/Clever/gearcmd/pull/67

We make this the default in order to match signal handling behavior in
sfncli (https://github.com/Clever/sfncli). We want to know ahead of time
if any application isn't handling sigterm correctly before moving to workflows.

Note: If this breaks application behavior, please

(0) set `pass-sigterm=false` in Dockerfile and redeploy
(1) add a note here
(2) let @xavi- or someone on eng-infra know

Thanks!
