auth: luarecords, enhance ifportup() with lists of sets of addresses like ifurlup()

[chbruyand]

Short description

This PR allows to provide ifportup() with both a list of addresses or a set of list of addresses thus allowing to prioritize some addresses over others like in ifurlup().

-- Examples:
ifportup(443, {'192.0.2.1', '192.0.2.2'})
ifportup(443, {{'192.0.2.1', '192.0.2.2'}, {'198.51.100.1'}})
