jixie Bid Adapter : adding handling of userSync urls sent from server…

… side (prebid#11217)

* Adapter does not seem capable of supporting advertiserDomains prebid#6650
added response comment and some trivial code.

* removed a blank line at the end of file
added a space behind the // in comments

* in response to comment from reviewer. add the aspect of advertiserdomain in unit tests

* added the code to get the keywords from the meta tags if available.

* WIP

* cleaned up

* correcting formatting errors from circleci

* sending floor to our backend for each bid, when available, changed one of the 1st party cookies that we want to send to backend

* fixed spacing issues in code

* 1/ provide the possibility of using the jixie section of the config object to determine what ids to read from cookie and to send
2/ removed ontimeout handling
3/ bidwon just ping the trackingUrl, if any
4/ misc: sending aid (from jixie config if any), prebid version etc

* corrected formatting mistakes

* adding support of handling usersync array from the server side

* add back registerBidder line dropped accidentally

* fixed some formatting flaws

* correcting more formatting issues

* more formatting corrections
