OnEarth v2.8.10

• Added ability to redirect to a backup static GetCapabilities document in the event of a failure to retrieve the document from the capabilities service.
• The time service now distinguishes between Redis errors and data not being found.
• Added support for clustered Redis environments.
• Added oe_best_redis.py, a Python replacement for best.lua. New unit tests for oe_best_redis.py have also been included.
• Fixed a bug in best.lua that would result in layers being erroneously re-added to the :best_config Redis key. This will likely be the final update made to best.lua. We recommend switching to using oe_best_redis.py.
• Fixed bug causing DescribeDomains to erroneously exclude a layer's first date from the results when performing requests for specific time ranges.
• Fixed LERC layers issues: LERC layers are now configured for 1 band by default, and the image/lerc mime type is now correctly handled
• Documentation updates
• Dependency updates
