CLI: make it more like psql (#2235)
* Refactor CLI to mimic psql's meta-commands

This PR adds support for meta-commands (also known as "backslash
commands") like those in psql, Postgres's CLI. Only a few meta-commands
are currently implemented, but this was meant to demonstrate how we
could use something like `\i file.csv` to insert local files into SQL
statements.

* Meta-commands: \file and \include

The initial implementation used `\i` as a streaming file handle.

This commit changes that to `\file`, and then implements `\i` (or
`\include`) as handling multiple sql commands.

* Add meta-command "help" (\?)

This is basically a copy of the psql help output, but includes only
those options we currently support.

* Add support for \o [file], and \timing

The \o meta-command writes query output to a file.

The \timing meta-command turns on/off the timing display sent to stdout.

* Add meta-commands: \l (show databases) and \dt (show tables)

* Add meta-command: \watch [period]

* Update meta-command \connect to take database name instead of ID

* Add support for \echo, \qecho, and \warn

This commit contains an known issue in that the `-n` option will exclude
the line feed, but if the output is the terminal, the readline package
clobbers any content on the current line (i.e. anything without a line
feed). That will need to be addressed at some point.

* Add support for \w [FILE] (write query buffer to file)

* Add SchemaAPI no-op implementation

* Refactor query handler to align with /sql and /databases endpoints

We want to standardize on:
/sql
/databases/{databaseID}/sql

* Add CLI support for expanded, border, tuples_only (and pset)

* Add help text for \pset and \t
