In the QueueSize test, it was possible that after the `done` channel was
closed, one of the queries from the queue would begin executing. If all
three began executing before the shutdown was done, the third would
block on attempting to send a value to the `executing` channel and it
would never finish so the controller would report that shutdown failed.
This increases the queue size to a combination of the concurrency quota
and the queue size so all of the started queries will never block when
sending a signal to the executing channel.
The storage table reader will now work correctly when there are multiple
outputs. The table interface now implements the new table and column
reader interfaces and works properly with `execute.CopyTable`. The
source uses `execute.CopyTable` to buffer the table in memory when there
are multiple output transformations.
The controller implementation is primarily used by influxdb so it
shouldn't be part of the flux repository. This copies the code from flux
to influxdb so it can be removed from the next flux release.
The `databases()` function was moved into the `influxdata/influxdb/v1`
package and so it wouldn't work anymore. The `percentile()` call was
changed to `quantile()` and the argument was changed to `q`. This also
updates `median()` to use `median()` since we now produce AST's and not
the spec so we can use the `median()` definition instead.
The RPC call should translate `_measurement` and `_field` to their
proper shortened byte strings when requesting the tag values.
This also fixes the planner rewrites to return the root node even when
no rewrite happened as this is required by the planner.
If a pattern is seen that matches the `v1.tagValues(...)` call, then it
will be replaced with a direct RPC call to read the tag values for the
selected tag key which should be better optimized than reading from the
storage engine tsm1 files.

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.
BucketsAccessed doesn't work currently with a private flux.Spec.
See this issue: https://github.com/influxdata/influxdb/issues/13278
This set of changes just allows code to compile until #13278 is fixed.
Note that preauthorization is not working in the meantime.
Fixes#13275.
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.
