Only Parse Used Created Policies from AWS

[ShubhamPalriwala]

Problem

Closes #729

Solution

Saved up a lot of pre-created default policies (adding 0 to the cloud costs) and their rows from the inventory.
ANDDD
Performance gains by an approx 10x 🚀
How:

• Before: Querying atleast 1000 predefined policies from 22 AWS zones
• After: Querying only user created policies (realistically worst case 100? ) from 22 AWS zones

Before

After

Notes

However, we still iterate through the 1000 something extra policies so there definites is a scope for efficiency and performance gains!
10x gains lesssgooo!
