Versions 2.6.*

What's new in version 2.6.0:

• JSON schema for our observe-agent.yaml config file. This makes editing the agent config much easier and safer.
• New config validate command which we can now use to validate our helm chart output.
• Added the groupbyattrsprocessor.
• All bundled config is now part of the build, so no need for all of the extra template files on disk.
