Title: #579: krb5 locator: add support for multiple addresses and sub-domains

I think the general intention of the patch is good and I like destructors being
used in general, but there seems to be a bug. When I send SIGUSR1 to sssd to
force it to go offline, sssd_be crashes:
```
Program received signal SIGUSR1, User defined signal 1.
