I was looking at this page: Bootstrap Examples Theme
at bottom of page the "Carousel" Item, the HTML Code on Line 600:
I want to know if holder.js is part of Bootstrap Framework or this code use some external js library to display this SVG images.

Nope, Bootstrap only provides its own JS and CSS.
As far as I know, holder.js is a JavaScript library that you can use to easily generate images of the size of your choice.
I guess Bootstrap used it to make some examples of how carousel renders.
