UTI: Export results

+ Model version 1.0.0.
- Only some result types are exported.
 + MRR, NDRPDR and SOAK.
 - Other result types to be added later.
 + In contrast, all test types are detected.
+ Convert custom classes to JSON-serializable equivalents.
 + Sort dict keys before converting to JSON.
  + Override the order for some known keys.
 + Export sets as sorted arrays.
+ Convert to info content from serialized raw content.
+ Also export outputs for suite setups and teardowns.
 + Info files for setup/teardown exist only temporarily.
 + The data is merged into suite.info.json file.
  + This simplifies presentation of total suite duration.
+ Define model via JSON schema:
 - Just test case, suite setup/teardown/suite to be added later.
 - Just info, raw to be added later.
 + Proper descriptions.
 + Json is generated from yaml.
  + This is a convenience for maintainers.
  + The officially used schema is the .json one.
 + TODOs written into a separate .txt file.
+ Validate exported instance against the schema.
 + Include format checking.
 + Update CSIT requirements for validation dependencies.
  + This needs python-dateutil==2.8.2, only a patch bump.
+ Compute bandwidth also for soak tests.
 + This unifies with NDRPDR to simplify schema definition.
 - PAL may need an update for parsing soak test message.
+ Include SSH log items, raw output only.
+ Generate all outputs in a single filesystem tree.
 + Move raw outputs into test_output_raw.tar.xz.
 + Rename existing tar with suites to generated_robot_files.tar.xz.
