Add UnderdogMedia Adapter

[baragona]

Hello,

We would like to add an adapter to support our Bidding API. The tests included use a mocked implementation of our Bidding API, therefore no contact with our server is needed to run the tests.

Here are the parameters our adapter supports:

• bidfloor (optional)
• siteId (required)

Here are some parameters than anyone is free to use to test our adapter:

{
    bidder: 'underdogmedia',
    params: {
       siteId: '10272'
    }
}

It should consistently return test bids for at least the 728x90, 300x250, 160x600 ad sizes.

If anyone has issues with this adapter please contact us at: [email protected]

Thanks,
Underdog Media

Reviewed, code looks good, tests are green, ads are returned. Thanks for the contribution.

Please note that PR #498 allows for passing a bid request when creating a bid response so that the IDs match. See that PR for details.

This spec includes the "qs" npm module but is not specified in package.json. Might want to add it.
