Tasks related to #578

[rubenthoms]

We have already implemented some of the features in #578 in https://github.com/CeetronSolutions/webviz-config/tree/EQ_578-new-plugin-layout (wc) and https://github.com/CeetronSolutions/webviz-core-components/tree/settings-menu-and-views-dash-adjusted (wcc). This issue gives an overview over the remaining tasks in both branches (since most of the work is overlapping).

difficult/time consuming 🔴🟠🟡🔵🟢 easy/quick

• 🟡 Create a more advanced/complex demo plugin / page (J&R)
• 🔵 Include contact person, screenshot filename, download and deprecation warnings in the new setup (WebvizPluginWrapper) (J)
• 🔵 Implement download and screenshot per view element (J)
• 🟠 Find a better way to generate screenshots and implement it in WebvizPluginWrapper (R)
• 🟢 Check if the new setup works with "old" plugins - make sure that the new layout does not come as a breaking change - if a plugin does not have the app member, the usual layout function should be used (J)
• 🔵 Implement full screen function for whole plugin (J)
• 🔴 Refactor how a plugin tour works in the new setup (with views) by keeping the old implementation working and implement it accordingy in React (J&R)
• 🟢 Adjust style of ToggleSettings button in WebvizSettingsDrawer to style of other buttons in this component (R)
• 🟠 Implement new View/SettingsGroup/ViewElement classes based on the aforeimplemented ABC classes which provide convenience functions for quickly creating new views, settings etc. (J&R)

view: WebvizView = WebvizPluginABC.make_view()
WebvizPluginABC.add_view(object_of_class_based_on_WebvizViewABC)

shared_settings_group: WebvizSharedSettingsGroup = WebvizPluginABC.make_shared_settings_group()
WebvizPluginABC.add_shared_settings_group(object_of_class_based_on_WebvizSharedSettingsGroupABC)

view_element: WebvizViewElement = WebvizView.make_view_element()
WebvizViewABC.add_view_element(object_of_class_based_on_WebvizViewElementABC)

settings_group: WebvizSharedSettingsGroup = WebvizViewABC.make_settings_group()
WebvizViewABC.add_settings_group(object_of_class_based_on_WebvizSharedSettingsGroupABC)
