Significant changes

Bindmounting Downloads

• As a BBS API client, I can specify that my DownloadAction on a Task or DesiredLRP is to be provided via a read-only bind-mount, and updated Diego Cells will respect that

Performance

• Investigate slamming the auctioneer directly

BBS API

• Fix backwards-incompatibility introduced in CellPresence models

App execution

• When Diego stops an instance, it should send TERM signals to all the remaining processes running in it before destroying the container
