Improves Query Condition to Document and Column

[otaviojava]

The proposal creates some improvements on a query to both, Column and Document types. So the idea is to create a mechanism to do a conditional query:
Ex:

Column age = Column.of("age", 26);
Column name = Column.of("name", "otavio");
ColumnCondition condition = ColumnCondition.eq(name).and(ColumnCondition.gte(age));

or:

ColumnCondition condition = ColumnCondition.eq(name).negate();

Following some databases, we will create reserved words, keywords, to each condition on org.jnosql.Condition enum. The formula is underscore plus condition name sensitive case.
So,

Column age = Column.of("age", 26);
 Column name = Column.of("name", "otavio");
ColumnCondition condition = ColumnCondition.eq(name).and(ColumnCondition.gte(age));

Will result from a Column that gonna have:
"_AND" as key and then a list these two conditions, name equals otavio and age greater or equals to 26.

Or:

ColumnCondition condition = ColumnCondition.eq(name).negate();

That will result in a documentation where the key is:
"_NOT" and the value gonna be the condition.
