Run Qt5 client sample test

[MartinDelille]

PR checklist

• Read the contribution guidelines.
• Ran the shell script under ./bin/ to update Petstore sample so that CIs can verify the change. (For instance, only need to run ./bin/{LANG}-petstore.sh, ./bin/openapi3/{LANG}-petstore.sh if updating the {LANG} (e.g. php, ruby, python, etc) code generator or {LANG} client's mustache templates). Windows batch files can be found in .\bin\windows\. If contributing template-only or documentation-only changes which will change sample output, be sure to build the project first.
• Filed the PR against the correct branch: master, 4.1.x, 5.0.x. Default: master.
• Copied the technical committee to review the pull request if your PR is targeting a particular programming language.

Description of the PR

I just added Qt5 PetStore sample test. I'm not sure Qt5 is installed on the CI so I'll fix it if not.

[MartinDelille]

Unfortunately, since I upgrade the qt5 client petstore example to openapi 3.0 spec, the test fails to compile: https://travis-ci.org/OpenAPITools/openapi-generator/builds/562992191#L5084

Should we revert #3400 ?

[etherealjoy]

Yes, Lets revert #3400 . I did not have a chance to compile it, and assumed it was done.
You can create the bug for the non compiling, It seems to be some mustache error.

[MartinDelille]

Done here: #3458

CircleCI job failed: do I need to install Qt for CircleCI too? It doesn't seems that the issue is related.

[etherealjoy]

I restarted the CI job and it passed.

Another option is to use drone.io that we just setup over the weekend: https://github.com/OpenAPITools/openapi-generator/blob/master/CI/.drone.yml

If there's a docker image with those dependencies installed, we can set it up very easily with drone.io.

@wing328
do you have more comments, looks fine for me.

[wing328]

No more feedback/question from me. The change looks good 👍

This might be due to memory leak fixed here: #3661
