Remove SomoAudience bid adapter

[bretg]

SomoAudience no longer supports their server-side adapter, so would like to drop it. Email below.

We discussed in PBS committee and agreed that the best way to remove an adapter is:

• make sure there's a way to put the biddercode on a "soft-error" list so publishers don't start getting 400 errors from Prebid Server if they're utilizing the code in their AdUnits
• then remove the adapter code from the repo

Hi Bret.,

We will not be maintaining the Somo Prebid adapter.  Let me know what steps I need to take to remove the Somo from prebid.  

TY,

Todd

@bretg Will Somo open a PR themselves to remove their adapter? That would be preferred. The "soft-error" list already exists in PBS-Go, Please see

prebid-server/exchange/adapter_util.go

Line 79 in 145499d

func GetDisabledBiddersErrorMessages(infos config.BidderInfos) map[string]string {

. A removed adapter is considered a disabled adapter with a custom error message indicating its removal from PBS. At some point in the future when enough time has passed we may decide to clean up these entries.

I doubt we'll get a PR from SomoAudience. I updated the docs side to get them off that list.
