making package testingutil and ui work for unit test build on windows

[prietyc123]

/kind bug

What versions of software are you using?

Operating System: windows

Output of odo version: master

How did you run odo exactly?

make test
Note: odo binary is not needed for this test

Actual behavior

Unit test build gets failed on windows for packages mentioned in the issue title.
More details : #2562 (comment)

Expected behavior

Unit test should pass.

It could be a proposed solution : tektoncd/cli#191

Any logs, error output, etc?

This is getting affected on windows due to #2586

testingutil and ui uses a pseudo terminal https://github.com/openshift/odo/blob/master/pkg/testingutil/survey_ui.go#L75 and which is executed by library github.com/Netflix/go-expect not supported on windows. AFAIF there is no similar library as github.com/Netflix/go-expect though we have an alternate way of doing this. We can replace github.com/kr/pty with github.com/creack/pty Refer - tektoncd/cli#191 . But unfortunately we don't have any option to replace it using glide. It can be done using replace in go mod.

Reason for build (https://travis-ci.com/github/openshift/odo/jobs/284808147) to get failed on windows in odo:

PS C:\Users\Admin\go\src\github.com\openshift\odo> go test -count=1 pkg/project/project.go pkg/project/project_test.go pkg/project/types.go

@kadel @girishramnani It would be great if you look into this and let me know if there is any suggestion for such use cases.
