Fix race in Celery tests by pre-creating result tables (apache#8909) We noticed our Celery tests failing sometimes with > (psycopg2.errors.UniqueViolation) duplicate key value violates unique > constraint "pg_type_typname_nsp_index" > DETAIL: Key (typname, typnamespace)=(celery_tasksetmeta, 2200) already exists It appears this is a race condition in SQLAlchemy's "create_all()" function, where it first checks which tables exist, builds up a list of `CREATE TABLE` statements, then issues them. Thus if two celery worker processes start at the same time, they will find the the table doesn't yet exist, and both try to create it. This is _probably_ a bug in SQLA, but this should be an easy enough fix here, to just ensure that the table exists before launching any Celery tasks.
Prepare release candidate for backport packages (apache#8891) After preparing the 2020.5.19 release candidate and reviewing the packages, some changes turned out to be necessary. Therefore the date was changed to 2020.5.20 with the folowing fixes: * cncf.kubernetes.example_dags were hard-coded and added for all packagesa and they were removed * Version suffix is only used to rename the binary packages not for the version itself * Release process description is updated with the release process * Package version is consistent - leading 0s are skipped in month and day
