branch-4.0: [fix](test) solve defined global variables in cloud_p0 suites

[hello-stephen]

Proposed changes

Issue Number: close #xxx

In several cloud_p0 regression test suites, resp was assigned without the def keyword, making it an implicit global variable. This could cause interference between test cases when tests run in the same Groovy script context.

Fix by:

1. Adding def keyword to declare resp as a local variable
2. Removing trailing semicolons for consistency

Affects 23 files under regression-test/suites/cloud_p0/.
