MMT-4002 & MMT-4017: Custom widget support for searching/selecting a KMS keyword

[cgokey]

Overview

What is the feature?

Support a custom widget for selecting a keyword from the form page.

What is the Solution?

Added a custom widget component that provides a tree for a user to search for keyword and select it. The selection will then populate the form page. You can also filter by concept scheme. The placeholder text mentions you can filter by UUID, but that is coming in the next ticket, as will require a KMS change.

What areas of the application does this impact?

Keyword Manager Form

Testing

Select a keyword from the tree, so the form displays.
Next to each keyword should be a pencil icon, indicating you can edit that keyword. Note the tree will open to the selected keyword.
Click it and a modal will display.
Try finding a keyword by searching by pattern, selecting it, and hitting accept. The form should now contain your selection. Note when you search, the tree now auto expands all nodes and highlights the search word.
