core: autopilot manager: bump memory limit to 200mb

[Williangalvani]

fix #2170

[Williangalvani]

autopilotmanager idles at ~ 25mb, the unzipped manifest file is 36mb. loading the whole thing as json in memory seems to be what is causing the large memory usage.
We can either merge this or try to find a better json parser.

The issue in the end is having both in memory at the same time. We can let it go since it happens only once with the manifest decompression.

In the end the problem was with gzip and not the json, @Williangalvani you can check the flamegraph plot.
