Closes #824 This implements statistics gathering across the various components, but ultimately this is for implementing a new CLI command: `container stats`. This shows memory usage, cpu usage, network and block i/o and the number of processes in the container. The new command can inspect stats for 1-N containers and by default continuously updates in a `top` like stream. ## Type of Change - [ ] Bug fix - [x] New feature - [ ] Breaking change - [ ] Documentation update ## Testing - [x] Tested locally - [x] Added/updated tests - [x] Added/updated docs
