b9b9cafa8f Expose a Registry type in health package, so unit tests can stay isolated from each other
Update docs.

Change health_test.go tests to create their own registries and register
the checks there. The tests now call CheckStatus directly instead of
polling the HTTP handler, which returns results from the default
registry.

b09b0ffcf9 Add configurable file-existence and HTTP health checks
Add a section to the config file called "health". Within this section,
"filecheckers" and "httpcheckers" list checks to run. Each check
specifies a file or URI, a time interval for the check, and a threshold
specifying how many times the check must fail to reach an unhealthy
state.

Document the new options in docs/configuration.md.

Add unit testing for both types of checkers. Add an UnregisterAll
function in the health package to support the unit tests, and an
Unregister function for consistency with Register.

Fix a string conversion problem in the health package's HTTP checker.

a68e081de4 Do not expose health check data in health handler
Because health check errors may expose sensitive data, we shouldn't expose the
details of the failure to clients. Instead, an error is returned to the client
with a hint about where they could find further information on why the service
is down.

6ba799b69e Provide simple storage driver health check
To ensure the ensure the web application is properly operating, we've added a
periodic health check for the storage driver. If the health check fails three
times in a row, the registry will serve 503 response status for any request
until the condition is resolved. The condition is reported in the response body
and via the /debug/health endpoint.

To ensure that all drivers will properly operate with this health check, a
function has been added to the driver testsuite.
