fix: ozzo validation

[injeniero]

OpenAPI required, nullable, min, max, minLength and maxLength influence how OZZO validation should be done.

This changes are in the direction described in the OpenAPI 3.0.3 clarification on how nullable property should work.

The following table summarize this PR interpretation of the spec on how it should be done using ozzo validations.

#	ozzo validation	type	required	nullable	min	max	minLength	format	pattern
1	Required	array	x				>0
2	Required	enum	x
3	Required	integer	x		>0
4	Required	integer	x			<0
5	Required	map	x				>0
6	Required	number	x		>0
7	Required	number	x			<0
8	Required	string	x				>0
9	Required	string	x					x
10	Required	string	x						x
11	NotNil	array	x
12	NotNil	map	x
13	NilOrNotEmpty	array					>0
14	NilOrNotEmpty	enum	x	x
15	NilOrNotEmpty	enum		x
16	NilOrNotEmpty	integer		x	>0
17	NilOrNotEmpty	integer		x		<0
18	NilOrNotEmpty	map					>0
19	NilOrNotEmpty	number		x	>0
20	NilOrNotEmpty	number		x		<0
21	NilOrNotEmpty	string		x			>0
22	NilOrNotEmpty	string	x	x				x
23	NilOrNotEmpty	string	x	x					x

@injeniero overall it looks good, but I need a bit more time to go through all of the changes and test it out locally, I am aiming that we have this merged no later than end of week
