Hey CC'ing @sambekar15 also to verify. I think the issue ticket is worded imprecisely which probably is adding to the confusion. If I understand the issue ticket correctly, we want to:

• return full lineage if no query param is present
• return full fw lineage if no query param for FW lineage is present
• return full bw lineage if no query param for BW lineage present

So for instance,
http://localhost:9000/v1/lineage/table/LOREM?bw=0 => return full FW lineage
http://localhost:9000/v1/lineage/table/LOREM?fw=0 => return full BW lineage
http://localhost:9000/v1/lineage/table/LOREM?fw=0&bw=0 => return empty lineage
http://localhost:9000/v1/lineage/table/LOREM?fw=1 => return fw @ depth 1, full BW lineage and so forth, right?

If that's the case, this fix won't achieve what we want to do
