ipsec: fix instance, and cli del for new ipsec interface
- use user instance number in interface name Restore the behavior of previous versions where the IPsec tunnel interface name contained the value of the user-provided instance number. For example, a command similar to create ipsec tunnel local-ip . . . instance 5 would result in the creation of interface "ipsec5". - ipsec: delete tunnel protection when asked The "ipsec tunnel protect" command will parse a "del" argument but does not undo the tunnel protection, leaving the SAs hanging around with reference counts that were incremented by a previous invocation of the command. Allow the tunnel protection to be deleted and also update the help text to indicate that deletion is an option. - test: ipsec: add test for ipsec interface instance Also cleanup (unconfig) after TestIpsecItf4 NULL algo test.
