It appears there are no environment variables to uniquely identify ionic environment. All appears to be generic.

if ci-info is not able to detect ionic envioronment. may be we can use this CI_APP_ID or CI_BUILD_NUMBER or CI_BUILD_ID variables to detect whether it is CI or not. but this can't be used to detect whether if it is running actually on ionic.

ci-info should be now detect appflow #84. Keeping this open since this issue is not completely addressed.
