When a docker image is built using `make`, it gets tagged as
`ysde:grafana-backup` and not as `alpinebased:grafana-backup`.

fix typo in README

This is important when mounting user volumes onto the container, so that
the generated output will be owned by the appropriate user id..

Some more minor mistakes that I missed..

1. Updated the list of the supported components of this tool.
2. Rewrote some text for better clarity.
3. Removed the specification of a Grafana version, as we are supporting every Grafana version there is (?).
4. Updated some URLs to official sites and fixed broken ones.

2) Fixed import statements - don't use `from x import *`, but import only what is needed.
2) Reformatted the code.

grafana spell incorrectly.

Without --rm, subsequent runs will fail with an error such as:

    docker: Error response from daemon: Conflict. The container name "/grafana-backup-tool" is already in use by container "e8a6c8a7b717dd52402ea75c7189002bbb80836ae641df1e9865e0f1ec7835b7". You have to remove (or rename) that container to be able to reuse that name.                                                             
    See 'docker run --help'.
