Add quotes around printed domain values

[lightseba]

The domain intervals can be ambiguous in cases like
SELECT * FROM table WHERE col >= 'a' AND col <= 'b'
vs.
SELECT * FROM table WHERE col = 'a, b'
which both have the domain interval [a, b].
This is fixed by adding quotes to the output (["a", "b"] vs. ["a, b"])
and escaping quotes which may appear in the string itself.
Also made PlanPrinter.formatDomain() use the formatting code in
Range.toString(), which is exactly the same.

Test plan
In addition to the unit tests added, I ran

CREATE TABLE test_orders WITH (partitioned_by = ARRAY['orderkey', 'processing']) AS 
SELECT custkey, orderkey, orderstatus = 'P' processing FROM orders WHERE orderkey < 3

EXPLAIN SELECT * FROM test_orders WHERE orderkey < 2 AND orderkey > 20

This query should show quotes around the domain intervals.

== RELEASE NOTES ==

General Changes
* Add double quotes around the column domain values in the text query plan. 
  Literal double quotes in values will be escaped with a backslash (ab"c -> ab\"c).

How about if if have field value as '<min>' or '<max>'? Please add a test for that.

As we talked, please add tests for lower level API range and higher level PlanPrinter. For each, try both cases of x in ('a','b') and x in ('a,b')

@lightseba This change has a user-visible impact. Please, add release notes to the PR description.

[mbasmanova]

the logic of adding quotes is repeated multiple times; consider adding a helper method that takes a buffer and a value to add and adds the value with quotes.

move this variable to top of the class; consider adding line breaks for readability, e.g. before .setTimeZoneKey, .setLegacyTimestamp, etc.
