ShellMixin sets the default timeout to 20min,This fixes a problem that will lead to `podman run` exiting prematurely at about 20mins in certain conditions.
The bug happens when:
- The original podman-helper is used
- The system podman sock is proxied via haproxy
It turns out that `podman run` without detach will wait for the container by calling the wait endpoint. Also, haproxy does not like it because it hangs for too long without producing any results, so it just terminates the connection. This leaves us in a situation where the container is still running, but `podman run` exits already. which is not enough to run libkazv's build processWe cannot reproduce this problem when using podman locally or podman-remote via the unix socket directly.
Type: fix
