* Drop BASE TABLE type in favour for just TABLE
This commit drops the table type 'BASE TABLE' and replaces all
occurences with just 'TABLE', since his type is wider-used and
friendlier to the client applications that query for certain table types
in their discovery mode.
The 'TABLE' type is also explicitely mentioned by the JDBC and ODBC
standards and although other data source-specific types are permitted,
older apps will not work well with them.
* Refactor table type constants out of IndexType
Move SQL_TABLE/_ALIAS out of IndexType, so that they can also be used in
that Enum definition.

Some functions act as shortcuts for more verbose declarations (sometimes
with certain constraints). This PR removes the boilerplate around
declaring such functions as well as a dedicated rule for the optimizer
to perform the actual substitution.

This is a simple naming change PR, to fix the fact that "metadata" is a
single English word, and for too long we have not followed general
naming conventions for it. We are also not consistent about it, for
example, METADATA instead of META_DATA if we were trying to be
consistent with MetaData (although METADATA is correct when considered
in the context of "metadata"). This was a simple find and replace across
the code base, only taking a few minutes to fix this naming issue
forever.
* EQL: Use In from QL
* EQL: Add more In tests
* EQL: Test In duplicates
* EQL: Add test for In mixed types
* EQL: Copy In translation to QL
* SQL: Use InComparisons from QL
* EQL: Remove boost checks from QueryFolderOkTests
* QL: Add TranslatorHandler.convert
Improve separation of scripting between EQL and SQL by delegating common
methods to QL. The context detection is determined based on the package
to avoid having repetitive class hierarchies.
The Painless whitelists have been improved so that the declaring class
is used instead of the inherited one.

EQL: Add Substring function with Python semantics (#53688)
Does not reuse substring from SQL due to the difference in semantics and
the accepted arguments.
Currently it is missing full integration tests as, due to the usage of
scripting, requires an actual integration test against a proper cluster
(and likely its own QA project).

Add missing asScript() implementation for LIKE/RLIKE expressions.
When LIKE/RLIKE are used for example in GROUP BY or are wrapped with
scalar functions in a WHERE clause, the translation must produce a
painless script which will be executed to implement the correct
behaviour and previously this was completely missing, and as a
consquence wrong results were silently (no error) returned.

This commit makes the names of fetch subphases more consistent:
* Now the names end in just 'Phase', whereas before some ended in
'FetchSubPhase'. This matches the query subphases like AggregationPhase.
* Some names include 'fetch' like FetchScorePhase to avoid ambiguity about what
they do.

This fixes:
- the parsing of milliseconds in intervals: everything past the . used to be converted as-is to milliseconds, with no normalisation of the unit; thus, a value of .23 ended up as 23 millis in the interval, instead of 230.
- the printing of a trailing .0, in case the interval lacks the fractional part;
- tests generating a random millisecond value used to simply print it in the string about to be evaluated without a necessary front-filling of 0[s], where the amount was below 100/10.
(The combination of first and last issues above, plus statistical "luck" made the incorrect handling pass the tests.)

While we use `== false` as a more visible form of boolean negation
(instead of `!`), the true case is implied and the true value does not
need to explicitly checked. This commit converts cases that have slipped
into the code checking for `== true`.
Previously, if YEAR() was used as and ORDER BY argument without being
wrapped with another scalar (e.g. YEAR(birth_date) + 10), no script
ordering was used but instead the underlying field (e.g. birth_date)
was used instead as a performance optimisation. This works correctly if
YEAR() is the only ORDER BY arg but if further args are used as tie
breakers for the ordering wrong results are produced. This is because
2 rows with the different birth_date but on the same year are not tied
as the underlying ordering is on birth_date and not on the
YEAR(birth_date), and the following ORDER BY args are ignored.
Remove this optimisation for YEAR() to avoid incorrect results in
such cases.
As a consequence another bug is revealed: scalar functions on top
of nested fields produce scripted sorting/filtering which is not yet
supported. In such cases no error was thrown but instead all values for
such nested fields were null and were passed to the script implementing
the sorting/filtering, producing incorrect results.
Detect such cases and throw a validation exception.

Extract reusable functionality from SQL into its own dedicated project QL.

removed
- several utility classes have been broken into base (QL) and extended

- operators (+,-,/,*) are
- due to extensibility, serialization of arithmetic operation has been
slightly changed and pushed down to the operator executor itself
