Investigate impact of increasing LSIF upload limit

Currently LSIF uploads are limited to 100MB. This creates a problem with larger projects looking to use code intelligence as the artifacts can easily grow beyond that limit.

Per this comment

I just want to confirm first if we use the limit before workhorse parses the input LSIF. This way, if we're sure that the limit is not considered at all when we parse input LSIF, the only tradeoff I see is increase storage usage. I want to do some testing on that but I'm not able to find time yet.

We need to test how the limit could impact Workhorse or other areas of the product before making a decision to increase it.
