ci: only kill containers that are based on the solanalabs/rust* images

[yihau]

Problem

I'm trying to migrate our ci environment into a single docker image. Kill all containers will kill the buildkite process as well. Also it seems too aggressive to kill all containers in the machine.

Summary of Changes

only kill containers that are based on the solanalabs/rust* images.

lgtm, just nits

on another note, seems like everything in this hook is hacks around behavior that we should try to correct?

yeah! I separate this script into 1) process killing and 2) cargo uninstall

for 1) I would like to just remove them and see do we encounter issues. these codes are added like 4y ago. maybe buildkite has already those issues 🤔

for 2) I guess I can remove them when the migration finish!

if i had to guess this is more likely to be hung tests not responding to the kill signal than some bk problem

probably. the problem isn't exactly clear from the comment. i get how cargo uses CARGO_HOME, but not what the conflict is that makes us want to uninstall these bins by force. worst case seem like the solution would be to install them in a custom dir and control that dir's priority in PATH 🤷
