Netgroup nisdomain and hosts validation

Browse Source 
nisdomain validation:
Added pattern to the 'nisdomain' parameter to validate the specified
nisdomain name. According to most common use cases the same pattern as
for netgroup should fit. Unit-tests added.

https://fedorahosted.org/freeipa/ticket/2448

'add_external_pre_callback' function was created to allow validation of
all external members. Validation is based on usage of objects primary
key parameter. The 'add_external_pre_callback' fucntion has to be called
directly from in the 'pre_callback' function. This change affects
netgroup, hbacrule and sudorule commands.

For hostname, the validator allows non-fqdn and underscore characters.
validate_hostname function in ipalib.util was modified and contains
additional option that allows hostname to contain underscore characters.
This option is disabled by default.

Unit-tests added.
