Description

In T259163#9350922 and below, it was confirmed that all legacy EventLogging MobileWikiApp* schemas and streams can be decommissioned.

These schemas were not migrated to Event Platform.

Once @SNowick_WMF confirms in a comment on this task, these can be decommissioned.

Add these schemas to the eventlogging_schemas_disabled list to prevent eventlogging-processor from producing these events.

Delete the data:

Delete the eventlogging_MobileWikiApp* topics from Kafka
Drop the event.MobileWikiApp* tables from Hive
Delete the /wmf/data/event/mobilewikiapp* directories from HDFS
Delete the /wmf/data/raw/eventlogging_legacy/eventlogging_MobileWikiApp* directories from HDFS
OPTIONAL: Delete the MobileAppWiki* metawiki schemas by editing them an emptying their content.

Oh, actually! There is only one remaining schema to migrate. Instead of specifically decomming these MobileWikiApp schemas, we can just finish up T238230: Decommission EventLogging backend components by migrating to MEP and turn off legacy eventlogging altogether!
