Popover instead of alert box on highlight click

[asn10038]

Change popup for a tag label from default alert box to bootstrap popover

https://getbootstrap.com/docs/4.0/components/popovers/

This can be done by:

• Including popover bootstrap lib
• Include data-toggle, data-content, etc attributes in the html when the highlight is rendered
• This should be done in the highlightTags() function in autoInternBase.js
