Add ability to create like condition as %value, value% and value without %

[vjik]

Currently, is avaliable only when manually escape value. See here:

db/src/QueryBuilder/Condition/Builder/LikeConditionBuilder.php

Line 87 in 03dc434

$escape === null ? $value : ('%' . strtr($value, $escape) . '%'),

What if we introduce $escape property in src/QueryBuilder/Condition/LikeCondition.php which by default will be equal to self::ESCAPE_BOTH constant. Also having ESCAPE_START, ESCAPE_END and ESCAPE_NONE as alternative values
