switch to plain mongo image

[nr23730]

This change migrates the mongo image from bitnami to the official mongo image from docker library.

Using that image should allow easier upgrades of mongo in the future.
In addition the official mongo image is available for multiple architecutres (including arm, which would allow the usage of AWS graviton nodes), while the bitnami one is only available on x86_64.

For further explanation:

The init.sh file is a copy of the original entrypoint of the docker image (https://github.com/docker-library/mongo/blob/56dd5c86b7a329b944845ea782fb98a3384d8d4e/4.0/docker-entrypoint.sh) with one change:

Replacing the last line

exec "$@"

with

cp -r /data/db/ /seed

This makes the builder terminate instead of run mongod after the initialization and saves the data to a save place (otherwise they are being deleted).

Thank you! @nr23730 Can I know how you spin up the database? We use this command to deploy database on kubernetes cluster (see doc):

helm install gn-mongo-v0dot31 bitnami/mongodb --version 7.3.1 --set image.repository=genomenexus/gn-mongo,image.tag=0.31_mutationassessor,persistence.size=100Gi,nodeSelector."eks\.amazonaws\.com/nodegroup"=eks-genome-nexus-database,tolerations[0].key="dedicated",tolerations[0].operator="Equal",tolerations[0].value="eks-genome-nexus-database",tolerations[0].effect="NoSchedule" --namespace genome-nexus

After using plain mongo image, can we still do it the same way?

I'm sorry, but I haven't deployed it on kubernetes.
