Implement configurable detach keys (for `attach`, exec`, `run` and
`start`) using the client-side configuration
- Adds a `--detach-keys` flag to `attach`, `exec`, `run` and `start`
commands.
- Adds a new configuration field (in `~/.docker/config.json`) to
configure the default escape keys for docker client.

This can be allowed because it should only restrict more per the seccomp docs, and multiple apps use it today.

Block kcmp, procees_vm_readv, process_vm_writev.
All these require CAP_PTRACE, and are only used for ptrace related
actions, so are not useful as we block ptrace.

The bpf syscall can load code into the kernel which may
persist beyond container lifecycle. Requires CAP_SYS_ADMIN
already.

a specific clock to be specified. Time is not namespaced, so do
not allow.

When a container is created it is registered before the mount is created. This can lead to mount does not exist errors when inspecting between create and mount.

RWLayer will now have more operations and be protected through a referenced type rather than always looked up by string in the layer store.
Separates creation of RWLayer (write capture layer) from mounting of the layer.
This allows mount labels to be applied after creation and allowing RWLayer objects to have the same lifespan as a container without performance regressions from requiring mount.
