Description

Instructions on how to use Flink with Hadoop are spread out over multiple pages:

• https://flink.apache.org/downloads.html
• https://ci.apache.org/projects/flink/flink-docs-release-1.9/flinkDev/building.html#hadoop-versions
• https://ci.apache.org/projects/flink/flink-docs-release-1.9/ops/deployment/hadoop.html

We should consolidate the information on a single page that we link to from elsewhere.

Additionally we should clarify under what circumstances the flink-shaded build instructions are useful, i.e., when exporting the hadoop classpath caused issues, a custom hadoop version is required etc.
