Sparse 1.2.0: Communication and task management improvements

This minor version improves the framework performance by proper utilization of asynchronous task loops.

• Implement communication with asyncio protocols.
• Use asynchronous task queue between rx pipe and task executor
• Implement dynamic server-side batching.
• Implement client pace steering with delays.

The following functionalities are no longer supported in the current version. In the future the support may be added, or they may be migrated to other repositories:

• Deprune example application (not tested after the recent changes)
• Fog offloading suite for example applications (will potentially be re-implemented in future releases)

Sparse 1.1.0, Deprune and K8S

This minor version release includes the following features:

• Deprune example application implementation.
• Assets for deploying example applications into k8s cluster.
• Utility scripts for configuring and deploying example applications in k8s.
• Removed jetson stats dependency in the sparse statistics -> (use tegrastats directly for gpu/power measurements).
