We're seeing intermittent issues with the environment.

An example run https://travis-ci.com/github/ovsrobot/dpdk/builds/217641063

Issue 1:
collect2: fatal error: ld terminated with signal 9 [Killed]

This suggest an issue with resources.

Issue 2:
ticketlock_autotest sometimes times out. This could be due variable resource availability in a container environment, but may not be.

There could be other issues, I haven't analysed all of the logs, but there are enough to make us want to switch to Graviton2 for all jobs.

We're don't see either issue with the Graviton2 environment (which uses VMs).
