[FEATURE] Threaded jobs

[dtaivpp]

At the moment every job will execute in series which could cause issues as one job failing would take down the pipeline and most jobs (of different types) could be run in parallel.

community-pulse should have a way to ensure that jobs of a similar type (eg. twitter) are executed in series so that they do not exhaust their API limits but jobs of dissimilar types are executed in parallel such that they do not block each other.
