Rebuilt custom images start warm from their first sandbox

A new build of an image starts at the sizes your account's other images use on that server, before any sandbox asks for them; only your own account's images count. On a test server, a rebuilt image's first 1 vCPU, 512 MiB sandbox started in 120 to 139 ms, where it took 2,364 ms. See fast starts.
