SHOW TAG VALUES does not return the correct results from all nodes in a fully replicated cluster (default config values).

Node 1:

> create database db
> use db
Using database db
> insert cpu,tk=tv value=1
> show tag values with key = "tk"
name: tkTagValues
-----------------
tk
tv

>

Node 2 (after all commands on node 1 have completed):

> show tag values with key = "tk"
name: tkTagValues
-----------------
tk
tv

>

Node 3 (after all commands on node 1 have completed):

> show tag values with key = "tk"
>

I'm going to start converting this to use the new query engine. It will depend on #5811 being merged first though.

`SHOW TAG VALUES` output has been modified to print the measurement name
for every measurement and to return the output in two columns: key and
value. An example output might be:

    > SHOW TAG VALUES WITH KEY IN (host, region)
    name: cpu
    ---------
    key     value
    host    server01
    region  useast

    name: mem
    ---------
    key     value
    host    server02
    region  useast

`measurementsByExpr` has been taught how to handle reserved keys (ones
with an underscore at the beginning) to allow reusing that function and
skipping over expressions that don't matter to the call.

Fixes #5593.
