Filter attributes neuron metrics

[aditya-purang]

Description of the issue

We saw that the EMF logs for neuron were having too many bytes causing an inflation in bills. This was caught by our monitoring and while investigating we saw some attributes which were redundant and could've been filtered out making the logs a bit lighter.

Description of changes

This PR has 2 major changes for the GPU processor:

1. We drop all the attributes from resource metrics object if they are coming from the DCGM or the neuron monitor scraper.
2. The attribute filtering logic has been moved from the neuron metric modifier to the gpu processor. It has now been combined with GPU metrics and the filters have been moved to a different files making the code a bit more readable.

Tests

Tested in eks playground cluster

Requirements

1. Run make fmt and make fmt-sh : done
2. Run make lint : done
