rinpatch 8c7a382027 Rename Pleroma.Mix.Tasks.Common -> Mix.Pleroma and import it's functions
instead of aliasing

This seems to be the convention for functions that can be reused between
different mix tasks in all Elixir projects I've seen and it gets rid on
an error message when someone runs mix pleroma.common

Also in this commit by accident:
- Move benchmark task under a proper namespace
- Insert a space after the prompt

## Replace embedded objects with their references
Replaces embedded objects with references to them in the `objects` table. Only needs to be ran once. The reason why this is not a migration is because it could significantly increase the database size after being ran, however after this `VACUUM FULL` will be able to reclaim about 20% (really depends on what is in the database, your mileage may vary) of the db size before the migration.
mix pleroma.database remove_embedded_objects
Options:
- `--vacuum` - run `VACUUM FULL` after the embedded objects are replaced with their references
## Prune old objects from the database
mix pleroma.database prune_objects
## Create a conversation for all existing DMs. Can be safely re-run.
mix pleroma.database bump_all_conversations
## Remove duplicated items from following and update followers count for all users
