Add system information to metadata

[perolavsvendsen]

In some cases, it is useful to know which version of fmu-dataio was used to produce certain metadata. We can probably also think of other system information which can be important context for generated data, and thus should be recorded in the metadata.

Suggest to include system information into produced metadata, starting with the fmu-dataio version used.

suggestion:

_sysinfo:
  fmu-dataio:
    version: 1.2.3

Consider putting this into tracklog to account for system information being different between events?

Ref comment, consider also adding:

• Operating system
• Host ID

Should be a simple task, lets get the schema in first. Depends upon #409

@perolavsvendsen I have made a PR that outlines how i think something like this(Add OS and Host ID) can be done w/Pydantic.
