Refactor old components

[PavelJankoski]

Summary

References #6376

Changes

List of refactored components:

• /pkg/webui/console/lib/components/with-feature-requirement.js -> removed
• /pkg/webui/console/containers/gateway-connection/gateway-connection-reactor.js -> removed
• /pkg/webui/lib/components/error-view.js -> As if now, there is no way to turn functional component into error boundary. Check this thread

Removed every usage of connect, except:

• pkg/webui/lib/components/full-view-error because useSelector cannot be used outside of redux Provider(there are two usages of that component outside Provider. pkg/webui/console.js and pkg/webui/account.js)
• pkg/webui/account/containers/collaborators-table and pkg/webui/console/containers/applications-table. Check what's the correct way to refactor when there is merge props used.

お疲れ様でした！

This is quite a large diff, so hard to review in detail. The end-to-end tests are passing though. I've checked it out locally as well and didn't see any warnings or issues. We should do some extra scrutiny once this is on staging.

• pkg/webui/lib/components/full-view-error because useSelector cannot be used outside of redux Provider(there are two usages of that component outside Provider. pkg/webui/console.js and pkg/webui/account.js)

That's fine.

• pkg/webui/account/containers/collaborators-table and pkg/webui/console/containers/applications-table. Check what's the correct way to refactor when there is merge props used.

Let's discuss in the frontend meeting.
