Allow RQ v2.0

[gabriels1234]

Hi @cunla

14.19 The conflict is caused by:
14.19     The user requested rq==2.0
14.19     django-tasks-scheduler 2.1.0 depends on rq<2.0 and >=1.16

I haven't tested, will try soon and update here.

Thanks!

I noticed some tests are failing with the new RQ 2.0.

@cunla been trying for a while to make it pass the tests, adding explicit connections when missing, but so far still wasn't able to make it work. will stay with rq==1.16.2 for the time being.
I don't know if to close the issue or to leave it open for someone to implement it? For better or worse this is the de-facto Django Admin interface for RQ.

Do not close it.. It emphasizes the importance of removing the dependency on RQ in this package.
