Parse servers logs from API

Summary:
rAPI811ec59e06b2 published the integral server log to
https://api.nasqueron.org/servers-log/all.json as
a static resource.

In the future, this will be updated to provide all
log entries dynamically or in cache.

Our website will consume this API JSON document in
client-side JavaScript and will then decorate the log
with links to relevant resources, like tasks or commits.

Test Plan:
Design has been reviewed by @Sandlayth, @rama, @Ash-Crow
and others. API client code tested against rAPI811ec59e06b2.
