Adds dill exclusion to Dockerfiles to accomodate upcoming beam fix (apache#15048)

* Upgrades moto to newer version (~=2.0)

According to getmoto/moto#3535 (comment)
1.3.17 version of moto with a fix to be compatible with mock> 4.0.3 is
not going to be released because of breaking changes. Therefore we need
to migrate to newer version of moto.

At the same time we can get rid of the old botocore limitation, which
was added apparently to handle some test errors. We are relying fully
on what boto3 depends on.

Upgrading dependencies also discovered that mysql tests need to
be fixed because upgraded version of dependencies cause some test
failure (those turned out to be badly written tests).

* Adds dill exclusion to Dockerfiles to accomodate upcoming beam fix

With the upcoming apache-beam change where mock library will be
removed from install dependencies, we will be able to remove
`apache-beam` exclusion in our CI scripts. This will be a final
step of cleaning dependencies so that we have a truly
golden set of constraints that will allow to install airflow
and all community managed providers (we managed to fix all those
dependency issues for all packages but apache-beam).

The fix apache/beam#14328 when merged
and Apache Beam is released will allow us to migrate to the new
version and get rid of the CI exclusion for beam.

Closes: apache#14994
