cs_project.py: pass cleanup=true in deleteProject API

[yadvr]

Pass cleanup=true in the delete project module, refer:
https://cloudstack.apache.org/api/apidocs-4.18/apis/deleteProject.html

code lgtm

the new flag was introduced in cloudstack 4.16, which breaks backwards compatibility somehow.
apache/cloudstack#4617

[resmo]

@weizhouapache well, didn't test it yet but in the past, cloudstack just ignored unknown flags? So for earlier versions, this shouldn't break backwards compatibility right?

@resmo
this PR also works with the earlier cloudstack versions which do not support the cleanup flag.

There will be a warning message in log (just a warning) like

Received unknown parameters for command deleteProject. Unknown parameters : cleanup

[resmo]

This should actually be a bool like so 'cleanup': True

[yadvr]

Sure @resmo I can fix that. Does ansible/module, convert boolen True to 'true' string when pass the args in the API call?
