RQL (part 1) - Match and search expressions

Description

Creates the Rule Query Language core language on top of the Rules.Framework rules engine, adding support for match and search expressions.

Some examples of the language usage (using the integration tests scenario 8 - poker combinations):

MATCH ONE RULE FOR "TexasHoldemPokerSingleCombinations" ON $2023-01-01Z$;

match one rule for "TexasHoldemPokerSingleCombinations" on $2023-01-01Z$ when { @NumberOfKings is 1, @NumberOfQueens is 1, @NumberOfJacks is 1, @NumberOfTens is 1, @NumberOfNines is 1, @KingOfClubs is true, @QueenOfDiamonds is true, @JackOfClubs is true, @TenOfHearts is true, @NineOfSpades is true };

SEARCH RULES FOR "TexasHoldemPokerSingleCombinations" SINCE $2023-01-01Z$ UNTIL $2023-01-31Z$ when { @NumberOfKings is 3 };

search rules for "TexasHoldemPokerSingleCombinations" since $2023-01-01Z$ until $2023-01-31Z$ when { @NumberOfAces is 5 };

It is also added a simple RQL commands prompt to the Web UI (sample image using the Web UI sample on the solution).

Related to #152.
