dynamic options: add data table filter

[bernt-matthias]

In a recent gitter discussion (https://gitter.im/galaxy-iuc/iuc?at=6190aeff8c019f0d0b93414b) it was asked for a way to have a select list containing only elements that are not yet in a data table.. Et voila .. there is a data table filter.

The test tool shows how it might be used:

1. the options are dynamically create from a file (from_file also had no test so far)
2. the filter removes all options that are already in the data table

For the first part I needed to apply a little hack: from_file seems to assume that the file is in tool-data in the Galaxy root. It would be much nicer if the file would be loaded from the dir (or a tool-data dir in this dir) containing the tool. Otherwise we would not meet the use case of the gitter discussion.

I did not think about other possible use cases (e.g. intersections of data tables) and possibly needed attributes...

The PR also adds more linting to filters.

I'm bumping this to 22.05, we still need to figure out what's up with https://github.com/galaxyproject/galaxy/pull/12941#discussion_r772962524

There's a conflict here and I think the framework test failure is legitimate ?
