Test reg_test_3765_ssl_pollout-t has a long history of failures, that probably are false positive.
The test modifies admin-stats_system_cpu while running the test itself.

I suggest a couple of changes:

• admin-stats_system_cpu should not be changed during the test itself
• admin-stats_system_cpu should be set to 5 as the default for the whole CI run ( @mirostauder )
• get_proxysql_cpu_usage() shouldn't modify admin-stats_system_cpu , it should be a read-only function as the name suggests
• get_proxysql_cpu_usage() should be more verbose , reporting with diag the last N (5?) entries of system_cpu , even if processes the last 2 entries
