[4.0.0] Bump minimum botocore version to 1.20.0 (#956)

[4.0.0] Bump minimum botocore version to 1.20.0

SUMMARY
With the next major version we can bump botocore/boto3 again.  Since 1.20.0 is now over a year old, we can bump the minimum version in preparation for 4.0.0.  CI should still test backports against the relevant versions for the backported release.
1.20.0 was released 2021-02-02.
1.21.0 was released 2021-07-15, hopefully we'll release 4.0.0 before July.
Should we release after mid-July we can always bump again.

 Starting with the 2.0.0 releases of amazon.aws and community.aws, it is generally the collection's policy to support the versions of `botocore` and `boto3` that were released 12 months prior to the most recent major collection release, following semantic versioning (for example, 2.0.0, 3.0.0).
 
-Version 3.0.0 of this collection supports `boto3 >= 1.16.0` and `botocore >= 1.19.0`
+Version 4.0.0 of this collection supports `boto3 >= 1.17.0` and `botocore >= 1.20.0`
