Expose new libzim settings to handle memory consumption #745
Description
openzim/libzim#950 moved some settings from env parameters to CPP exposed settings. This has been released in libzim 9.3.0.
openzim/libzim#960, openzim/libzim#974, openzim/libzim#975 and openzim/libzim#982 pushed this further by allowing to configure the memory we want to consume. This is planned to be released in libzim 9.4.0.
These settings should be exposed in kiwix-tools as well.
Should we release kiwix-tools without this issue handled, it means that we will introduce a kind of regression since environment variables available in the past (and used in our infra) are not here anymore, and there is no new way to do the same thing.
This is a companion issue of kiwix/libkiwix#1199
