Version 2.4.0

This release contains required configuration updates for existing SFM instances. It is important to review the sfm-docker release notes carefully before upgrading from versions before 2.4

Changes in this release:

• This release introduces support for hosting data volumes on different filesystems, rather than as subdirectories in a single sfm-data directory (#1051). This allows RabbitMQ, Postgres, and SFM data for exports, containers, and collection sets to be separately configured. Thank you, @SvenLieber, for code contributions to add this feature! For existing SFM instances, please read carefully the sfm-docker release notes for required configuration changes.
• Allows seeds to be deleted or undeleted while the collection is not active. Thanks for reporting this bug, @SvenLieber! (#1052)
• Upgrades Django to 2.2.24 and updates djangorestframework. (#1043, #1049)
• Upgrades Twarc version to fix bug with retweet text in CSV exports. (#1042)

Documentation updates:

• Updates Amazon Web Services EC2 installation instructions. (#1068)
• Explains new data volume configuration strategy. (#1051)
• Explains required number of seeds in Twitter search collections. (#1052)
• Adds directions on using JWAT Tools. (#1078)
