[Meta] Release v1.5

[msm-cert]

This time we have a help of actual programmers, so expect increased reliability and a better UI.

The list looks overwhelming, but many issues should be relatively straightforward (refactoring, small tweaks). The biggest feature is the planned infrastructure for automated indexing.

Database and performance:

• Create proper enums for Job statuses #370
• Optimize db.get_job_matches to paginate on the DB side #372
• Store job files in the database instead of ursadb iterators #381
• Refactor database handling in /api/job endpoint #394
• Add the information about match context to the database #395
• Initialize the database automatically when starting mquery #402

User interface:

• Show matched strings in matched samples #38
• Ellipsis hides matched-rules badges #196
• Better handling of dataset not found error #204
• Implement some "hint" banners in the admin panel #307
• Show the information about matches in the frontend. #396
• Migrate away from create-react-app #397

Management features:

There is also large project related to automated indexing here. The following issues are all related, but also obsolete and. This idea need to be redesigned, and shouldn't be worked on right now.

• Create a reindexing daemon. #142
• [Question] indexing samples automatically when added /samples folder #220
• Scan Certain Directories #223
• TODO design this properly and split into a list of issues

Bugfixes and chores:

• Make Dockerfiles more cacheable #75
• Bump frontend dependencies, and ensure that the project still works #400
• Bump backend dependencies, and ensure the project still works #401
• UrsaDB process gets killed on big set of files #222 (this will probably be closed as unreproducible)
• Improve the installation procedure #232
• Use the default config of auto-formatting tools #238 and Consider sorting imports with isort #256
