feat(cache): Add default fetch for loading cache to simplify usage

• chore: Increment package version to 1.2.6 SNAPSHOT

• feat(services): add nid and new release fields to projects model

• feat(cache): Add default fetch for loading cache to simplify usage

When using the Loading Cache Manager, previously you had to pass a full cache key for all requests. This led to additional logic being needed if there is a single HA value being stored.

To get around this, a default method was added that uses the runtime boot key value or a generic value to fetch the value, using only the inner class type to properly lookup the value.
