Use fs.onedatarestfs for Onedata files source plugin implementation

[lopiola]

The fs.onedatarestfs depends on a simple REST-based client for the Onedata system. The fs.onedatafs that was in the codebase until now was not a viable option - it could not be easily installed using pip due to the giant amount of dependent libraries, many of which were in C/C++.

How to test the changes?

(Select all options that apply)

• I've included appropriate automated tests.

• This is a refactoring of components with existing test coverage.

• Instructions for manual testing are as follows:

  1. Add the fs.onedatarestfs package to currently used requirements (can be found in conditional-requirements.txt).
  2. Create file_sources_conf.yml file in the config dir, copy the part concerning onedata from file_sources_conf.yml.sample.
  3. Create user_preferences_extra_conf.yml file in the config dir, copy the part concerning onedata from user_preferences_extra_conf.yml.sample.
  4. Create galaxy.yml file in the config dir with the following content

  galaxy:
    file_sources_config_file: file_sources_conf.yml
    user_preferences_extra_conf_path: user_preferences_extra_conf.yml
  

  5. Start the galaxy server, log in.
  6. You will need an account in a Onedata system instance. I'll be happy to provide you with a test account if that's desired. Then, it's enough to place the Onezone domain and your access token in the Galaxy's User Information panel and you are good to go.

There are no automated tests, as I believe specific file source plugins are not automatically tested.

Thanks for updating the package and making this PR. Should greatly ease the pain of setting things up.

Can you please also change the ConditionalDependencies.check_fs_onedatafs method name to fs_onedatarestfs in lib/galaxy/dependencies/__init__.py ?
This will allow the automatic installation of the conditional Python dependency.

lgtm!
