report the approximate hardware specs (CPU speed, cores, memory)
of the server in the /info endpoint. This may be useful when
benchmarking.
We do some workarounds because gopsutil's core count output is
confusingly different between Linux and Darwin, and the MHz output
is usually wrong on Linux. Intel's app notes say to just parse
the model string. Whyyyyyyy.
I'd like to add stat tracking to Roaring, which means it
has to be able to import the stats package, which means
stats has to be a package rather than part of the pilosa
package. If stats stops being in pilosa, it still needs
a way to import logger, so logger also has to leave the
pilosa package. Then everything using them needs to import
them and use package selectors on their names.
This doesn't actually add the stats support to roaring,
it just makes it so there's a way to import the stats
code from something in the roaring package.
This commit removes the previous `MaxShard` tracking and replaces
it with an `Available Shards` set tracking. This allows sparse shard
tracking without implicitly tracking all shards in between.
the RangeEnabled option now has no effect, but it still exists in the API. A few
tests still use it to ensure this. This would only be considered a breaking
change if someone was relying on Pilosa to enforce the RangeEnabled: false
option to prevent fields being created in certain frames. This seems unlikely.
