Datagrid Tree - Make Filtered child rows a setting

[tmcconechy]

Describe the bug
As a continuation on #1281

To Reproduce
Steps to reproduce the behavior:
Behavior number 2 still happens when you apply filter that match the parent node. Expand/collapse button is displayed but doesn't do anything.
Steps:

• Go to https://4140-beta0-enterprise.demo.design.infor.com/components/datagrid/test-tree-filter.html
• Apply Contains filter on Task column with the word "HMM"
• Try to Expand/Collapse the first row, nothing happens.

Expected behavior
Make this behavior a setting.

Add this as api settings allowChildExpandOnMatch: boolean

allowChildExpandOnMatch === true

• if only parent got match then add children nodes too

• if one or more child node got match then add parent node and all the children nodes
  allowChildExpandOnMatch === false

• if only parent got match then (disable|hide|anything-else) +/- button and no add children nodes

• if one or more child node got match then add parent node and only matching children nodes (as it doing now)

Additional context

Added to the sprint as Deepak is done with all the issues (except infor-design/enterprise-ng#206 which may not be possible) and he was working on fixing this.
