Add notification triggers support

[bblaisATcoveo]

Add the possibility to display an information message on top of the search box to provide additional details using the notification trigger mechanism.

TEST CASE 1
Prerequisite : a 'notification trigger' must be configured on the backend with proper conditions
1- Open the search results page, english version
2- Perform a search that match the condition of a trigger
3- A notification should appear under the search box in english

TEST CASE 2
Prerequisite : a 'notification trigger' must be configured on the backend with proper conditions
1- Open the search results page, french version
2- Perform a search that match the condition of a trigger
3- A notification should appear under the search box in french

This is missing the focusToView update so that the trigger receives focus upon display instead of being bypassed to the Query summary

@bblaisATcoveo Can you please add steps to reproduce? If I need to change stuff on the page to get a working example locally, this will need to be addressed by creating a page with a working example. Thanks!

@Garneauma Test cases were added. Notifications are entirely driven by configs on the backend only so we can use srb-en.html or sb-fr.html for testing

[Garneauma]

@bblaisATcoveo What are the patterns available so I can test?

[Garneauma]

@bblaisATcoveo As-tu un exemple pour en français? J'ai juste "sign in", mais le message est en anglais dans la page en français.

@GormFrank Added a notification trigger for French "se connecter". It works as expected.
