Fixes Issue

Fixes #2228
Fixes #2231

Changes proposed

Moved the logic to update run_schemas and dataset_schemas into Horreum logic and as a consequence I removed the following entities:

Triggers:

• ds_after_insert
• rs_after_run_untrash
• rs_after_run_update
• before_schema_update

Functions:

• ds_after_dataset_insert_func
• rs_after_run_update
• before_schema_update_func

I kept the procedure update_run_schemas in the db as it is always called by the Horreum directly.

Additionally with commit 714223f I removed the remaining triggers on Run table:

• after_run_update_non_data, moved logic into Horreum
• delete_run_validations, we are not even allowing Runs to be deleted so no need to keep that

With commit d18fcc7 I also removed all triggers associated to the label table:

• lv_before_update
• lv_after_update
• recalc_labels

And related functions. Moreover I also deleted the label_recalc_queue table as no longer used.

Preconditions

• This PR is based on Remove view recalc queue #2203, therefore we have to merge that first and then rebase this one.
