Description of problem:
Consider the following call

async_task(::Actions::BulkAction, ::Actions::Katello::Repository::Sync, [::Katello::Repository.librar.first], skip_metadata_check: true)

What ends up happening is that keyword arguments like 'skip_metadata_check' gets converted from symbols to string when BulkAction passes to the Sync.

Actions like sync expect expect them to be symbols like {:skip_metadata_check => true} but what gets passed to it from BulkActions is

making all kwargs passed to it useless.

How reproducible:

Steps to Reproduce:
1.In the console run the following line (assuming you have at least one repo)

ForemanTasks.sync_task(::Actions::BulkAction, ::Actions::Katello::Repository::Sync, [::Katello::Repository.library.first], skip_metadata_check: true)

2. Go to https://<sat-fqdn>/foreman_tasks/dynflow
3. Check the stopped and uncheck the pending and filter the search
4. You should see tasks Actions::Katello::Repository::Sync followed by Actions::BulkAction
5. Click show on the sync task
6. Check the params sent to the Actions::Katello::Repository::Sync
7. See the value set for skip_metadata_check
Actual results:
skip_metadata_check: false

Expected results:
skip_metadata_check: true

Additional info:

Any bulk action that accepts key word arguments are affected by this.
