Ubuntu20

[NelsonVides]

Ubuntu machines in CircleCI are updated to use 20.04, python2 and pip2 are not used anymore, and the docker image is built with phusion/focal-1.0.0-alpha1-amd64 (needs esl/mongooseim-docker#40 be merged first).

Seems like dropping the s3-parallel-put plugin increments times to upload results from ~40s to ~2min40s 😕
With and Without the plugin.
BUT, after raising awscli concurrency like in 54aa0bd, now uploading results are much closer to the old value, at around ~1min, like here

The changes look good, especially getting rid of Python 2.
Could you add the description to this PR?
Also, what is the plan with Travis?

Updated the description, but we need to first merge the PR for the mim-docker repo. About Travis, don't really know, I could try updating it to use focal as well, but it's taking really ages to run so it'd take forever to iterate on it, and we might drop it... Maybe it could be a separate task to update travis as well

I only meant running the tests on travis, I see they were canceled. I am also thinking we might drop Travis soon with its recent changes, but for now maybe we should just build it on Travis without changing the settings there.

Done

[chrzaszcz]

The changes look good. The docker image runs correctly, shows the right OS version and MongooseIM accepts connections.

We agreed that from now on the Travis builds are not necessary, so I am merging this one.
