Finishes the refactoring started in c1bbd8d. The goal of the refactoring is
to change the argument to get_realm from a Realm.domain to a
Realm.string_id. The steps were
* Add a new function, get_realm_by_string_id.
* Change all calls to get_realm to use get_realm_by_string_id instead.
* Remove get_realm.
* (This commit) Rename get_realm_by_string_id to get_realm.
Part of a larger migration to remove the Realm.domain field entirely.
This adds support for running a Zulip production server with each
realm on its own unique subdomain, e.g. https://realm_name.example.com.
This patch includes a ton of important features:
* Configuring the Zulip sesion middleware to issue cookier correctly
for the subdomains case.
* Throwing an error if the user tries to visit an invalid subdomain.
* Runs a portion of the Casper tests with REALMS_HAVE_SUBDOMAINS
enabled to test the subdomain signup process.
* Updating our integrations documentation to refer to the current subdomain.
* Enforces that users can only login to the subdomain of their realm
(but does not restrict the API; that will be tightened in a future commit).
Note that toggling settings.REALMS_HAVE_SUBDOMAINS on a live server is
not supported without manual intervention (the main problem will be
adding "subdomain" values for all the existing realms).
[substantially modified by tabbott as part of merging]
In write_log_line, error_content can be binary_type and
error_content_iter can be a Sequence of binary_type. Handle
this this in a python 3 compatible way. Also change annotations
to reflect this fact.
This will make it slightly easier to consume the data from our clients.

Previously, we counted not just the time required to process a
particular request, but also the time required to import+find the view
function via urls.py. The latter is usually fast, but when a new
Django thread starts up, it can take significant time, resulting in us
flagging slow requests on each server restart and also when a new
Django thread starts up on prod to handle requests.
This change means that we no longer include that startup time as part
of request processing time -- but we still log it in the case that it
was more than 5ms, so that we can identify why a particular request
was slower than expected if high startup times become a problem. We
annotate the time in log lines as "+start" rather than just "start" to
make clear that it's not counted in the total.
