The value of svcDhcpLseStateLeaseSplitActive indicates
whether or not the current lease time resulted from a
lease split.
If svcDhcpLseStateLeaseSplitActive is 'true',
the lease time passed to the client is determined by the
value of the object sapTlsDhcpProxyLeaseTime for VPLS SAPs,
or by the value of the object vRtrIfDHCPProxyLeaseTime
for Layer 3 interfaces.
