For #5172

As we've dropped support for go 1.8 (see 1.5.0 release post),
now we need to ensure that a minimum of go 1.9 builds correctly.

Fix all the resting errors to have a valid swagger file.

They are still some warnings but nothing blocking.

Doing so I found that some request still misses son parameters for some POST/PUT/PATCH request. This means the a client generated from the swagger file will not work completely. 

Fix #4088 by activating validation in drone
Should fix #4010.

Needed to access go tool gxz

* Use Golang 1.8 for build and test

If we state Golang 1.8 we should test using that version as well

* Use golang 1.8 only for single build to see if everything compiles

* Restore make test target

* make build -> go build

* remove test coverage on release/*

Otherwise drone may combine the logs
