Installation documentation: obsolete docker environment variables?

[wagner-intevation]

These three environment variables seem to have no effect:

intelmq/docs/user/installation.rst

Line 190 in 79cae29

sudo docker run -e INTELMQ_IS_DOCKER="true" \

intelmq/docs/user/installation.rst

Line 192 in 79cae29

-e INTELMQ_PIPELINE_BROKER: "redis" \

intelmq/docs/user/installation.rst

Line 194 in 79cae29

-e INTELMQ_PIPELINE_HOST: redis \

IIRC they were made obsolete by the generic solution to set parameters with env variables (INTELMQ_SOURCE_PIPELINE_HOST etc.)

INTELMQ_PIPELINE_HOST is being used, but INTELMQ_SOURCE_PIPELINE_BROKER, INTELMQ_DESTIONATION_PIPELINE_BROKER, INTELMQ_SOURCE_PIPELINE_HOST, INTELMQ_DESTINATION_PIPELINE_HOST and INTELMQ_REDIS_CACHE_HOST are not used.

PR is on the way
