[CI] Canary is hanging-up #4363

Description

Despite recently upping the timeout to 60 minutes, canary runs occasionally get stuck.

Since it happens with legacy tests (where we do not timeout command execution) we unfortunately have very little information.

TestCopyToContainer and TestCopyFromContainer do finish.

Presumably, another container test is stuck.

Two things could be done:

• continue rewriting container tests
• diff the hung build with the list of tests from a successful build to figure out which one is the offending test
