The ProxyQueryServiceAsyncBridge was not returning statistics when there
was an encoder error. Because the encoder was just writing to an
io.Writer, it was possible that a remote disconnect could happen and
statistics could not be reported.
It is no longer necessary for the query logging to be a bridge as the
stats are available for consumption from the ProxyQueryService.
This change changes the logging bridge to directly implement the proxy
query service instead of implementing a bridge.
I did this with a dumb editor macro, so some comments changed too.
Also rename root package from platform to influxdb.
In interest of minimizing risk, anyone importing the root package has
now aliased it to "platform" so that no changes beyond imports were
necessary in those files.
Lastly, replace the old platform module to local path /dev/null so that
nobody can accidentally reintroduce a platform dependency while
migrating platform code to influxdb.
Moves idpe.QueryService into platform/query.ProxyQueryService
Splits the Request into ProxyRequest and Request.
Changes query.QueryService and query.AsyncQueryService to use a Request
type. This means that the Compiler interface is consumed by the service
to abstract out transpilation vs Flux compilation vs raw spec.
The transpiler handler is removed.
There are separate http handlers and service implementations for each of
the three query services.
Query logging types are moved into platform.
The ResultIterator now expects Cancel to always be called.
The fluxd binary exposes the query endpoint specified in the swagger
file.
