#12808 Add support for 'Skip errors' validation strategy

[JustBeYou]

Description

I added in the validation phase of CVS importing some checks about validation strategy. Now, if the validation strategy is chosen to be 'Skip errors', the CVS file will be imported if the invalid rows number is smaller or equal to the number of allowed errors. In the previous versions, even if this option is selected, the data validation will fail if any invalid row is found.

Fixed Issues (if relevant)

1. Magento 2.2.2-dev - CSV Import, skip errors not working #12808: Magento 2.2.2-dev - CSV Import, skip errors not working

Manual testing scenarios

1. Download this CSV https://transfer.sh/PGiN8/catalog_product.csv
2. Go to Import section
3. Select 'Products' and 'Add/Update'
4. Select 'Skip Errors' and type '5' as 'Allowed Error Count'
5. Import the downloaded CSV and look how the validation pass even that there are 2 invalid rows

Unfortunately in this type of release (a PR to 2.2-develop is considered a Patch release) we cannot change interface classes because of our BiC guidelines. It would be a good idea to add a new interface and migrate any similar methods to this new interface (see http://devdocs.magento.com/guides/v2.2/contributor-guide/backward-compatible-development/index.html#introduction-of-a-method-to-a-class-or-interface for more information)
