All views: Add a magnifying glass icon in any search box

[C2H5-M]

It would be good to see a search icon embedded in any search box throughout the website (including searchable dropdown lists like Organizations in the Data&Analytics views). This would provide the user with a clearer starting point.

Discussed with the PO, since this is a type ahead not a search bar, the acceptance criteria is to add a place holder instead of a magnifying glass.
