@summary
Returns boolean based on kind and value.
@return
boolean values `true` or `false`
Valid kinds are `macaddress`, `netmask`, `ipaddress` and `network`.
@example **Usage**
has_interface_with("macaddress", "x:x:x:x:x:x") # Returns `false`
has_interface_with("ipaddress", "127.0.0.1") # Returns `true`
@example If no "kind" is given, then the presence of the interface is checked:
has_interface_with("lo") # Returns `true`
