[ Maestro ] Config entry changes update

Hello,

We are pleased to inform you that we have migrated from early-access to production[1]
instance of maestro API and it's been running smoothly for a while now.

This instance is stable and we usually update it weekly (on Mondays).

We recently updated configuration entries in maestro to rename all the "early-access"
entries with "production".
Here is a list of PRs for this transition:
- https://github.com/kernelci/kernelci-pipeline/pull/757
- https://github.com/kernelci/kernelci-core/pull/2638
- https://github.com/kernelci/kernelci-project/pull/488

Please make sure to use the below change in maestro pipeline TOML configuration[2]
file to accommodate this change if you are using the production API instance:
```
api_config = "production"
storage_config = "production"
```

Also, use the below change in your "kci" tool setup config file[3] if you wish to connect
with production API instance:
```
api = "production"
```
( Here[4] is the "kci" tool setup instructions for reference. )

Please let us know in case of any queries or comments.

Thank you,
Jeny Sadadia
