This line shows up as about 5% of cpu time on a synchrotron:
not_known_entities = set(entities) - set(self._entity_to_key)
Presumably the problem here is that _entity_to_key can be largeish, and
building a set for its keys every time this function is called is slow.
Here we rewrite the logic to avoid building so many sets.
This default config is parsed and used a base before the actual
config is overlaid, so with these values not commented out, the
code to detect when no turn params were set and refuse to generate
credentials was never firing because the dummy default was always set.
* Use more portable syntax using attrs package.
Newer syntax
attr.ib(factory=dict)
is just a syntactic sugar for
attr.ib(default=attr.Factory(dict))
It was introduced in newest version of attrs package (18.1.0)
and doesn't work with older versions.
We should either require minimum version of attrs to be 18.1.0,
or use older (slightly more verbose) syntax.
Requiring newest version is not a good solution because
Linux distributions may have older version of attrs (17.4.0 in Fedora 28),
and requiring to build (and package)
newer version just to use newer syntactic sugar in only one test
is just too much.
It's much better to fix that test to use older syntax.

We need to do a bit more validation when we get a server name, but don't want
to be re-doing it all over the shop, so factor out a separate
parse_and_validate_server_name, and do the extra validation.
Also, use it to verify the server name in the config file.
a61738b removed a call to run_on_reactor from a unit test, but that call was
doing something useful, in making the function in question asynchronous.
Reinstate the call and add a check that we are testing what we wanted to be
testing.
