added test for map variables
@amgorb The Travis CI testing is failing. Are you reporting a bug or just enriching the test suite? Please always be explicit.
@agentzh Yep, tests are failing because this bug isnt fixed yep: https://travis-ci.org/openresty/lua-upstream-nginx-module/jobs/187700844.
To clarify more: this issue https://github.com/openresty/lua-upstream-nginx-module/issues/39 descibed a bug in upstream.current_upstream_name which fails to display upstream name if scheme is set via variable
The test case in this pullreq will pass when issue will be fixed. Cant find the exact problem location
@amgorb I cannot merge a PR with failing tests to break our workflow. A corresponding fix is required.
