🌱 Install capi-operator as a turtles dependency in a dev-env

[Danil-Grigorev]

What this PR does / why we need it:

Improves dev environment setup for turtles, making it use actual turtles chart capi-operator as a dependency, as opposed to installing upstream one separately.

This allows to rely on CAPIProvider versions when deploying providers, so incompatibility in providers matrix is eliminated based on centralization of the providers version management.

Additionally this makes dev-env adhere to supported configuration described in turtles docs (more closely), and improves development process for etcd snapshot restore and other features.
