v2.6.0

This release brings many improvements for deploying custom images to Scrapy Cloud, particularly for non-Scrapy crawlers.

Enhancements:

• Extend onboarding wizard to include custom image configuration
• Use images.scrapinghub.com as default registry for custom images

• Test custom images before pushing them
• Add -S/--skip-tests parameter to shub image push and shub image upload
• Rewrite custom image docs
• Improve documentation of environment variables available on Scrapy Cloud
• Add singleton configuration (project: as shortcut to projects: default and similar for stacks)
• Rewrite configuration docs
• Unify how subcommands are called within shub
• Add parsing for new job URL format, adjust printed job URLs
• Create setup.py on shub image init instead of shub image build

Deprecations:

• Deprecate images section in scrapinghub.yml in favor of global default image and optional per-project configuration, and fail on ambiguous configurations
• Deprecate --async parameter for shub image deploy
• Deprecate --base-deps parameter for shub image init

Bugfixes:

• Fix requirements and trove classifier in setup.py
• Various smaller fixes throughout the docs
• Improve error output on shub image init without Scrapy project
