Commit 34a39b9070 introduced the
"linux.intelRdt.enableMonitoring" field. This patch supplements it by
adding "linux.intelRdt.monitoring" field in the features.json to check
if the runtime implementation supports the new field of the spec.

* config-linux: add schemata field to IntelRdt
Add a new "schemata" field to the Linux IntelRdt configuration. This
addresses the complexity of separate schema fields and resolves the
issue of supporting currently uncovered RDT features like L2 cache
allocation and CDP (Code and Data Prioritization).
The new field is for specifying the complete schemata (all schemas) to
be written to the schemata file in Linux resctrl fs. The aim is for
simple usage and runtime implementation (by not requiring any
parsing/filtering of data or otherwise re-implement parsing or
validation of the Linux resctrl interface) and also to support all RDT
features now and in the future (i.e. schemas like L2, L2CODE, L2DATA,
L3CODE and L3DATA and who knows L4 or something else in the future).
Behavior of existing fields is not changed but it is required that the
new schemata field is applied last.

Add `features.md` and `features-linux.md`, to formalize the `runc features` JSON that was introduced in runc v1.1.0.
A runtime caller MAY use this JSON to detect the features implemented by the runtime.
The spec corresponds to https://github.com/opencontainers/runc/blob/v1.1.0/types/features/features.go
(opencontainers/runc PR 3296, opencontainers/runc PR 3310)
Differences since runc v1.1.0:
- Add `.linux.intelRdt.enabled` field
- Add `.linux.cgroup.rdma` field
- Add `.linux.seccomp.knownFlags` and `.linux.seccomp.supportedFlags` fields (Implemented in runc PR 3588)
