Fix edgex-ui-go to use new go modules build job

[anonymouse64]

The edgex-ui-go master branch recently switched to using go modules, and now has jenkins jobs failing. See for example: https://jenkins.edgexfoundry.org/job/edgex-ui-go-master-verify-go/46/console from edgexfoundry/edgex-ui-go#85

I think the reason for this is that the default version of go is too old and doesn't support modules by default, and so we need to use the updated version of go that we use for i.e. edgex-go. AFAICT, for the edgex-go jobs this is accomplished in the job definition yaml with this snippet:

ci-management/jjb/edgex-go/edgex-go.yaml

Lines 8 to 13 in 457179d

	stream:
	- 'master':
	branch: 'master'
	pre_build_script: !include-raw-escape: shell/install_custom_golang.sh
	build_script: 'make test && make build docker'
	go-root: '/opt/go-custom/go'

Does that mean all we need to do to get this to work on edgex-ui-go is to add that go-root spec to the master stream?

Yes, I think you'll need the install_custom_golang.sh script and the go-root definition. But it looks like edgex-ui-go.yaml has a global pre_build_script already defined, so you'll need to make sure that overwriting that won't break anything.

After adding those to the master stream for edgex-ui-go, unfortunately the build still fails, however it seems the issue could be with some missing dependencies not checked into the go.mod file. I am investigating with edgexfoundry/edgex-ui-go#87
