[Tracker] Base Config Compatibility

[RobDolinMS]

(copied from roadmap.md)
Ensure that the base configuration format is viable for various platforms
Systems:

• Solaris
• Windows
• Linux

[vbatts]

We'll need some folks to contribute the technical requirements for these platforms, as Linux is what is currently getting our attention.

Currently comparing the Spec structs from:

• https://github.com/opencontainers/runtime-spec/blob/master/specs-go/config.go
• https://github.com/docker/docker/blob/master/libcontainerd/windowsoci/oci_windows.go

Have been in-touch with Jesse from Oracle and expecting more info soon.

Looks like this needs to be addressed before 1.0, I'm adding it to 1.0 milestone.

@RobDolinMS as you're heading this effort up, can you make a call on whether or not the final round of cleanup in PR #673 is enough to close the issue out? If not, please let me know what else I can do to wrap this up.

Since #673 was merged I'm going to close this as resolved. If this is not the case please open actionable issues that can be addressed.
