When looking for an Implementation renderer considers all TypeInstances available in the system

[lukaszo]

Description

There is a TypeInstance with AWS credentials available in the system. It's not used in any Policy and is not passed when creating an Action.

When creating a new Action, for example cap.interface.database.postgresql.install, renderer chooses an Implementation for AWS. The installation fails because there was no TypeInstance with credentials passed to the Implementation.

Expected behavior

Render should choose Helm based Implementation.

Actual behavior

Render notices that TypeInstance with AWS credentials is available and decides to use RDS Implementation.

Steps to reproduce

1. Create TypeInstance with AWS credentials
2. Create Action for installing a database: cap.interface.database.postgresql.install
3. Wait for it to be Ready to run and run it.
4. It should fail.

Proposed solution

Instead of using all available TypeInstances consider only TypeInstance passed via Policy or directly by user.
Currently TypeInstances are get here

typeInstanceValues, err := e.listCurrentTypeInstanceValues(ctx)
