feat: index validation without order

[TorstenDittmann]

Ignores query order for validation.

These Queries are Allowed:

• A,B,C
• A,C,B
• B,A,C
• B,C,A
• C,A,B
• C,B,A

Previous implementation only allowed following Queries:

• A,B,C

This will make Indexes more accessible 👍🏻

For the sake of our records. This PR has changed to tackle only the index orders limitation. Queries with proper indexes will be accepted now regardless of the attributes order inside the index.

Covering indexes if accepted, will be tackled in a separate PR.
