This changes the current use of the InfluxDB client to instead use a
baked-in client that uses the fasthttp library.
This allows for significantly smaller allocations, the re-use of http
body buffers, and the re-use of the actual bytes of the line-protocol
metric representations.
I don't like this behavior, but it's what InfluxDB accepts, so the
telegraf listener should be consistent with that.
I accidentally reverted this behavior when I refactored the telegraf
metric representation earlier in this release cycle.
in this commit:
- chunks out the http request body to avoid making very large
allocations.
- establishes a limit for the maximum http request body size that the
listener will accept.
- utilizes a pool of byte buffers to reduce GC pressure.
in this commit:
- centralize logging output handler.
- set global Info/Debug/Error log levels based on config file or flags.
- remove per-plugin debug arg handling.
- add a I!, D!, or E! to every log message.
- add configuration option to specify where to send logs.
closes#1786
also remove locking around adding metrics. Instead, keep a waitgroup on
the ServeHTTP function and wait for that to finish before returning from
the Stop() function
