[Libosinfo] [osinfo-db PATCH v2 1/6] schema: Add 'inherit' attribute to resources element

[Fabiano Fidêncio]

By adding this attribute we'll start having a way to allow resources
inheritance between OSes and its absence will be considered as "false".

An example of how it'll look like is:
foo:
  <resources arch="all">
    <minimum>
      <n_cpus>1</n_cpus>
      <storage>123456789</storage>
    </minimum>
  </resources>

bar (which derives-from/clones foo):
  <resources arch="all" inherit="true">
    <minimum>
      <n_cpus>3</n_cpus>
      <ram>12345678</ram>
    </minimum>
  </resources>

When querying for bar' minimum resources we should get:
n_cpus: 3
cpu: -1 (not set)
ram: 12345678
storage: 123456789

It means, basically all value *non* set for bar, will inherit the value
that's set for foo (in case we have any).

For the cases where we don't want to inherit something, we should do:
foo:
  <resources arch="all">
    <minimum>
      <n_cpus>1</n_cpus>
      <storage>123456789</storage>
    </minimum>
  </resources>

bar (which derives-from/clones foo):
  <resources arch="all" inherit="false">
    <minimum>
      <n_cpus>3</n_cpus>
      <ram>12345678</ram>
    </minimum>
  </resources>

When querying for bar' minimum resources we should get:
n_cpus: 3
cpu: -1 (not set)
ram: 12345678
storage: -1 (not set)
