Unable to use @memoized cache when call get_security_groups

[wei.ying]

Env: devstack master branch

Description:

The memoized function needs to use tuples as parameters [1].

Currently [2] the security_groups attribute in the port object, whose type is list,
when clicking the port details, a warning message appears:
"UnhashableKeyWarning: The key ((<weakref at 0x7ff5da258520; to 'DetailView' at 0x7ff5da275790>, []), ()) is not hashable and cannot be memoized.
WARNING:py.warnings:UnhashableKeyWarning: The key ((<weakref at 0x7ff5da258520; to 'DetailView' at 0x7ff5da275790>, []), ()) is not hashable and cannot be memoized."

    Fix UnhashableKeyWarning when calling get_security_groups function

    Memoized caches function specifies use tuples as parameters because
    lists are not hashable. When the get_security_groups function is called,
    the list type parameter is passed in, this causing fail to use memoized
    and the console appears UnhashableKeyWarning.
