Add the name of the SRv6 locator to use with IS-IS to the per-area SRv6 configuration. If an SRv6 locator is not configured for an IS-IS instance, the locator name is an empty string. When an IS-IS instance is configured to use an SRv6 locator, the locator name stores the name of the selected locator. Subsequent commits will add the possibility to set and unset an SRv6 locator for a specific IS-IS instance. Signed-off-by: Carmine Scarpitta <carmine.scarpitta@uniroma2.it>
