records.config to records.yaml (#9264)

This commit contains:

* records.yaml - Rename records that will have issues when migrated to
yaml.

To avoid issues with fields which the main root key holds value and also children fields I had to rename them in order to make it compatible with YAML.

So fields like this:

proxy.config.exec_thread.autoconfig INT 1 << can’t have value and children fields
proxy.config.exec_thread.autoconfig.scale FLOAT 1.0

So this now looks like this:

proxy.config.exec_thread.autoconfig.enabled INT 1

So when migrated to YAML it will looks like this:

exec_thread:
    autoconfig:
      enabled: 1 << new field.
      scale: 1.0

* records.yaml: replace records.config configuration file and use YAML
format instead.
- This change keeps the original internals and only adds a new layer for parsing YAML instead of records.
- YAML nodes are converted to record names (dot(.) separated) and use the same internal features.
- traffic_ctl still works with record names.
- All the internal API to query and set records remains unchanged.

* record.yaml - Add basic unit test for some specific cases.
* Add test for fields with multipliers
* Docs update.
