Module vmm_sys_util::metric

The purpose of this module is to provide abstractions for working with metrics in the context of rust-vmm components where there is a strong need to have metrics as an optional feature.

As multiple stakeholders are using these components, there are also questions regarding the serialization format, as metrics are expected to be flexible enough to allow different formatting, serialization and writers. When using the rust-vmm metrics, the expectation is that VMMs built on top of these components can choose what metrics they’re interested in and also can add their own custom metrics without the need to maintain forks.
