James Rodewig f51f8ed04c [DOCS] Remove unneeded options from `[source,sql]` code blocks (#42759)
In AsciiDoc, `subs="attributes,callouts,macros"` options were required
to render `include-tagged::` in a code block.

With elastic/docs#827, Elasticsearch Reference documentation migrated
from AsciiDoc to Asciidoctor.

In Asciidoctor, the `subs="attributes,callouts,macros"` options are no
longer needed to render `include-tagged::` in a code block. This commit
removes those unneeded options.

Drops some inline callouts that snuck into 7.x. We're doings this in

IIF(a = 1, 'one', 'many')

SQL: Implement CASE... WHEN... THEN... ELSE... END (#41349)
Implement the ANSI SQL CASE expression which provides the if/else
functionality common to most programming languages.

The CASE expression can have multiple WHEN branches and becomes a
powerful tool for SQL queries as it can be used in SELECT, WHERE,
GROUP BY, HAVING and ORDER BY clauses.

Costin Leau 61f49af497 SQL: Spec tests now use classpath discovery (#40388)
To avoid having to specify each spec by hand (which can miss specs to be
added), the test infrastructure now performs classpath discovery so that
each spec added, is automatically considered.

SQL: Implement GREATEST and LEAST functions (#35879)
Add GREATEST(expr1, expr2, ... exprN) and LEAST(expr1, expr2, exprN)
functions which are in the family of CONDITIONAL functions.

Implementation follows PostgreSQL behaviour, so the functions return
`NULL` when all of their arguments evaluate to `NULL`.

Renamed `CoalescePipe` and `CoalesceProcessor` to `ConditionalPipe` and
`ConditionalProcessor` respectively, to be able to reuse them for
`Greatest` and `Least` evaluations. To achieve that `ConditionalOperation`
has been added to differentiate between the functionalities at execution
time.
