This allows any datetime function to be present in `EXTRACT` which feels
more consistent. `EXTRACT(FOO FROM bar)` is now just sugar for
`FOO(bar)`. This is *much* simpler to explain in the documentation then
"these 10 fields are supported by extract and they are the same as this
subset of the datetime functions."
The implementation of this is a little simpler then the old way. Instead
of resolving the function in the parser we create an
`UnresolvedFunction` that looks *almost* just like what we'd create for
a single argument function and resolve the function in the `Analyzer`.
This feels like a net positive as it allows us to group `EXTRACT`
resolution failures with other function resolution failures.
This also creates `UnresolvedFunctionTests` and
`UnresolvedAttributeTests`. I had to create `UnresolvedFunctionTests`
because `UnreolvedFunction` now has three boolean parameters which is
incompatible with the generic `NodeSubclassTests`'s requirement that all
ctor parameters be unique. I created `UnresolvedAttributeTests` because
I didn't want `UnresolvedFunctionTests` to call `NodeSubclassTests` and
figured that we'd want `UnresolvedAttributeTest` eventually and now felt
like as good a time as any.

We don't need the double quotes. Also, we follow up with an example that
shows how to write them in yml.

Introduce system commands as alternative to meta HTTP endpoints
Pass in cluster name
Use 'BASE TABLE' instead of 'INDEX' when describing a table to stick
with the SQL terminology

Adds documentation for all of the date time functions using the new
cli-like format extracted from the csv spec. In the process of doing
this I noticed that the `WEEK` function isn't exposed as a function.
This exposes it for consistency.

I went to write some docs for datetime functions that look like:
```
SELECT YEAR(CAST('2018-01-19T10:23:27Z' AS TIMESTAMP)) as year;
year
2018
```
because I figured they'd be pretty easy to read because they didn't
require any knowledge of a data set. But it turns out that constant
folding doesn't work properly for date time functions because they don't
actually apply the extraction.

Adds a mode parameter to all SQL-related requests. The mode parameter is used for license checks as well as to define the response content. For now only two modes are supported plain (default) and jdbc. We will add other modes in the future as we add more clients.

* SQL: Move shared REST client methods to shared-client
This commit is a preliminary step for moving JDBC to the REST client. It extracts the common REST clients from CLI and moves it to shared-client. This will allow us to move to the 5 project setup: rest-proto, shared-client, server, jdbc, cli with the following dependencies:
server <-- rest-proto
shared-client <-- rest-proto
jdbc <-- shared-client
cli <-- shared-client

* Starts to build the list of supported functions, adding links to
wikipedia when there is any doubt what the functions mean.
* Extracts an example of using the function from the test suite.
* Explicitly calls out how we round (half up) because there are
lots of ways to round.
Original commit: elastic/x-pack-elasticsearch@5fb64ba869
* Remove "overview". That is already covered in the index page.
* Write a basic getting started page.
* Fix the CLI startup instructions.

This commits adds a new end point for closing in-flight cursors, it also ensures that all cursors are properly closed by adding after test checks that ensures that we don't leave any search context open.

The /_sql endpoint now returns the results in the text format by default. Structured formats are also supported using the format parameter or accept header similar to _cat endpoints.

Adds the option to specify an elasticsearch filter in addition to the SQL query by introducing a filter parameter in the REST query which would create a boolean filter if the SQL query generates an elasticsearch query or a constant score query if SQL if the SQL query doesn't generates an elasticsearch query. Usage:
{
"query": "SELECT * FROM index",
"filter" : { "term" : { "tag" : "tech" } }
}

1. decouple JdbcDriver from other classes to not trigger static
initialization (this happens through JDBC service discovery)
2. reduce visibility of JdbcDriver#close so only on jar unloading it
gets triggered
3. mark 3 methods introduced in Jdbc 4.1 as unsupported (their semantics
are somewhat weird)
4. Move versioning info in one class
5. Hook Version class in both JDBC entry points to perform cp sanity
checks
6. Remove JdbcDataSource#close (DebugLog are closed when the Driver gets
unloaded by the DriverManager) as there can be multiple instances of DS
but only one for Driver known by the DriverManager
Replace Strings with constants
Properly set TZ in security tests as well
JdbcDataSource is more defensive with its internal properties
JdbcConfiguration password parameter is aligned with JDBC DriverManager
Remove usage of JdbcConnection API
Removed JdbcConnection#setTimeZone - this encourages folks to use our
private API which would tie us down.
It is somewhat limiting for folks but it has less downsides overall and
does not trip debugging (which adds a proxy unaware of this method).
Update docs
Add JdbcDataSource into the Jdbc suite
Original commit: elastic/x-pack-elasticsearch@c713665d53
The keywords inside SqlBase are now sorted alphabetically - much easier
to read and update the docs
Original commit: elastic/x-pack-elasticsearch@5aa89c5950
Adds docs for the REST API, translate API, the CLI, and JDBC.
Next we need to add more example queries and documentation for our
extensions.
