Immutable DataPlaneInstanceStore

[wolf4ood]

Feature Request

Implements a static DataPlaneInstanceStore that can be configured with EDC settings and be immutable once initialized

Which Areas Would Be Affected?

Data plane selector

Why Is the Feature Desired?

For some scenario where the runtime flexibility provided by the DataPlaneInstanceStore it's not need,
an implementation of a configurable DataPlaneInstanceStore could simplify instances setup, without requiring users to write
custom extensions or some migration mechanism for handling their DataPlaneInstance data.

Solution Proposal

A new extension could be introduced that implements the DataPlaneInstanceStore which will be driven by configuration.

At startup time the extension loads the configuration and it creates an immutable version of DataPlaneInstanceStore.

The configuration could leverage the same mechanism used in the DataSource configuration by partition a certain level of the Config for configuring
multiple DataPlaneInstance.
