Improve config and reduce fulltest

[LouisLeNezet]

The truth variants set of NA12878 is now the one computed by Genome in a Bottle.

Why this change? I am confused as the reason behind this.

[atrigila]

I mean, we are going to launch a completely different AWS mega test from the one before.

[LouisLeNezet]

The aim is to reduce the computational cost of the megatest as much as possible.
The glimpse2 software as less steps (no variant calling) and should also be more computationally efficient.
I'll add it to the changelog

[atrigila]

While I may have some reservations about these changes, I also don’t want to block progress toward the release. I trust your verification that the full glimpse2 megatest works, that it is less computationally expensive, and aligns with the new genome in a bottle VCF :)

[LouisLeNezet]

I've checked on my cluster on a subset and everything worked perfectly ;)
After time verification glimpse2 run with 24% less time than glimpse1.
