Description of change

Making changes in Conversant bid adapter to use userIdAsEids
Refer: https://github.com/prebid/Prebid.js/blob/master/modules/userId/eids.md
Please note that for TDID, I have added ext field as well, I referred prebidServerBidAdapter for that.
Old format was

{
        source: 'adserver.org',
        uids: [{
            id: 'some-random-id-value',
            atype: 1
        }]
    }

New format is

{
        source: 'adserver.org',
        uids: [{
            id: 'some-random-id-value',
            atype: 1,
            ext: {
                rtiPartner: 'TDID'
            }
        }]
    }
