9.1.0

Feature

• Extend the internal proxy capabilities, now the target is overridable and SSL aware @sneridagh
• Added new environment variables for the internal proxy RAZZLE_PROXY_REWRITE_TARGET and RAZZLE_PROXY_REWRITE_TARGET @sneridagh
• Enhance AppExtras component to make it pluggable through the
  config.settings.appExtras. These are router-path filtered components that
  are rendered inside the AppExtras component @tiberiuichim

Bugfix

• Fix Sentry tags and extra via settings.sentryOptions @avoinea
• Fix yarn analyze command by packing our own version of
  webpack-bundle-analyzer integration. It has a few changes to the old default
  configuration. There is an alternative way of triggering the bundle analyzer,
  with the OFFLINE_BUNDLE_ANALYZE=true env variable, which avoids starting
  the HTTP bundle analyzer server. Also, it always saves a report html file.
