+ Flushes the learned IP multicast groups for the logical switch
+ identified by <var>switch</var>, which may be given as a UUID or
+ as a datapath name. If <var>switch</var> is not specified, flushes
+ learned multicast groups for all logical switches.

+ This works by incrementing the <code>seq_no</code> column of
+ the <code>IP_Multicast</code> record for the datapath.
+ <code>ovn-controller</code> monitors this value and flushes
+ its locally learned multicast groups when it detects a change.
