Expose actual guest HW description in guest topology

[happz]

Related to https://github.com/teemtee/tmt/issues/2402. The patch bootstraps hardware field in the guest topology content, and populates it it very basic content. Extending it with more info, e.g. disk or system, will be task for future patches.

In tmt-test-topology-Get-guest-data-default-0.yaml, I get something like this :

guest:
    name: default-0
    role:
    hostname: 127.0.0.1
    hardware:
        arch: == x86_64
        memory: == 8192000 kB
        disk[0].size: == 50 GB

Why == is included? Is it by design ?

It is included by default. The value of each requirement consists of the actual value, x86_64, and an optional operator, like = or !=. When the operator is missing, = is the default. arch: x86_64 and arch: = x86_64 are equivalent.

One thing that's wrong though, it should be =, not ==, that I need to fix.
