Create persistent docker volume for NCBI nt database rather than system mount

@Hobbeist set up a docker volume for the NCBI nt database and mount that with read permissions to overcome the docker permission error in the blast step of the pipeline.

copying files over to a volume (moby/moby#25245):

docker container create --name dummy -v myvolume:/root hello-world
docker cp c:\myfolder\myfile.txt dummy:/root/myfile.txt
docker rm dummy

Create a volume in a dedicated path:

docker volume create --opt type=none --opt o=bind --opt device=/data/volumes/testvol testvol
