Full API access to inspect and update instances in Charts

Today there is limited to no API access to Charts, creating several issues.

One obvious issue is that we cannot automate the setup of Charts. Eg, when an anomaly detection method detects an issue, we would like to be able to auto-create the Charts with the necessary timeseries, timerange, calculations and overlay anomaly insight (CogniteActivity extension). This is not possible today (only pre-build url with instances and range).

But another issue is around the maintainability of Charts. Due to the limit on the number or Views/revisions, we need to deprecate and delete old revisions on a regular basis (in particular in periods with heavy data model development). As far as I have seen, Atlas, Canvas and Chart lock the View version to the latest version (or maybe based on the location filter) during config. 
For Atlas agents and Canvas’ we can find the View versions via the API, allowing us to identify users depending on models that are deprecated, and also auto-duplicate with the updated versions/views. However, with Charts this is not possible. If Charts is supposed to only be a do-my-analysis-and-then-throw-it-away tool, that is ok, but if it is intended to be used for more long term analysis (it does offer functionality for this like calculations and threshold monitoring) we need a way to monitor status and update the views/instances in the Charts on an enterprise level (via API)
