Validation of minItems/maxItems array query parameter options

[oloose]

I am using the minItems and maxItems options for an array query parameter. The request validation does not automatically respond with a 400 Bad Request as I would expect when sending a request with less or more values as defined by the options.

Example request:

• /pet/findByTags?tags=test1 (less than minItems)
• /pet/findByTags?tags=test1,test2,test3,test4,test5,test6 (more than maxItems)

Expected behaviour

Server request validation automatically rejects the request and responds with 400 Bad Request.

@seseloos I will implement it soon or later

My upcoming pull request will contain:

• The behaviour of this new validator constrain
• A more than maxItems, less than minItems and in range test case
• New test spec elements
• Updated documentation
• Updated auto generator code files
