Bug description:

Hi,

We have a need for the popover to have a dynamically working autoClose property. Currently looking at the ngbootstrap, the autoClose value is being used only during the opening of the popover. However, we have the use case where some action means that the popover can temporarily not be closed for the popover that is currently being displayed. An example use case is if some action inside the popover triggers a server call, and we want to keep the popover open with a small spinner in the corner until the server response is returned.

Cheers,
Tom.
