Prepare a staging ideas deployment

[lubojr]

Will still utilize the testing branch approach, but will serve a new catalog containing all ideas indicators in order to soften the inclusion into existing dashboards.

• create a new ideas testing branch
• merge staging into current ideas_i4
• prepare ideas catalog deployment - YAMLs
• prepare ideas dashboard config (similar approach as polar.js) -> decided to add to corresponding catalogs instead
• solve merge conflicts
• review assets (place them to assets folder)

• IDEAS assets were migrated.
• Catalog PR feat: add IDEAS yamls eodash-catalog#189 adding these datasets to individual catalogs can be merged after adaptation of the metadata for the to-be-included indicators
• Client PR bringing the functionality of minesweeper and other new tools Ideas staging merge #2672 was tested with staging and merged.

Work on this is done. A follow-up email to partners will explain how to use this PR deployment for fine tuning metadata yamls and and how to use it in a story.
