support for multiple pbf files and resource limits for init pods

==Nominatim==
it would be nice to be able to initialize nominatim with multiple pbf files. If time permits I will submit a PR with that feature.
One other thing I noticed when using the chart is the initjobs get evicted due to resource constraints. To address this adding resource limits to the init containers should help.

I will try to take a look at it.

Hi, is there some new development or instructions regarding the feature for setting up multiple pbfs?

Hello, I'm also looking if there's a solution for this.

Sorry. No progress so far.
