             Summary: Add support for creation and coordination of local Sidecar Jobs 
                 Key: CASSSIDECAR-378
                 URL: https://issues.apache.org/jira/browse/CASSSIDECAR-378
             Project: Sidecar for Apache Cassandra
          Issue Type: Sub-task
            Reporter: Andrés Beck-Ruiz


To complement operational jobs, we need to create a {{LocalJob}} abstract class that represents a job being conducted on a Cassandra node that is managed by the Sidecar instance. Similar to the {{{}[OperationalJob|https://github.com/apache/cassandra-sidecar/blob/trunk/server/src/main/java/org/apache/cassandra/sidecar/job/OperationalJob.java#L199]{}}}, any {{LocalJob}} implementations must define the job logic in an execute or executeInternal function. For example, a {{RestartJob}} would call out to the {{LifecycleManager}} to stop and start a local node. 

We should also implement the {{{}LocalJobManager{}}}, which will create a new {{LocalJob}} when the {{LocalJobCoordinator}} detects that the Sidecar instance should execute a job that is part of a larger operational job. By default, we will implement the {{{}StorageLocalJobCoordinator{}}}, which will handle coordination by periodically polling the {{StorageProvider}} to monitor any new operational jobs. This can be implemented using the {{[PeriodicTask|https://github.com/apache/cassandra-sidecar/blob/trunk/server/src/main/java/org/apache/cassandra/sidecar/tasks/PeriodicTask.java]}} interface. The {{LocalJobCoordinator}} will also be responsible for updating the status of a {{{}LocalJob{}}}; for the {{{}StorageLocalJobCoordinator{}}}, this will entail updating local job state in the {{{}StorageProvider{}}}.
