Test Nuxeo Deployment on Graviton2

Context

Current Continuous benchmarks are run against C4.xlarge AWS instances that use x86 based CPUs.
It would be good to have a sense of how our stack behaves on ARM based Graviton2 Instances types.

Get a baseline

It would be useful to get a first performance baseline.

We can start this experimentation by running the standard benchmark on a c6g instance type.
This may be as simple as changing the deployment to replace
c4.xlarge by c6g.xlarge.

Looking at the instances types:

c4.xlarge	4 cores / 7.5 GiB	  => $0.199 per Hour
c6g.xlarge	4 cores / 8 GiB      => $0.136 per Hour

This means that cost goes down by 30% so if performance is similar or close enough, this may be an interesting path to follow.
