Radware LBaaS v2 driver LB deletion fails when no members exist

[Evgeny Fedoruk]

Radware defined as a LBaaS v2 provider.

LB instance created with or without lister(s)/ pool(s)
No members created for LB pool(s)

LB is deleted.
Radware driver tries to delete LB service on back-end system and fails because no LB is created on back-end system until at least one member is defined for the LB.
