feat(clover): add Joi validations

[jkeiser]

This PR adds Joi validations for scalars:

• number: minimum, maximum, exclusiveMinimum, exclusiveMaximum, multipleOf
• string: minLength, maxLength, pattern, format: date-time/timestamp/uri

It does this by:

1. prop.joiValidationGenerating the Joi validation expression (Joi.string().max(255).pattern(new RegExp("^arn:"))) based on the type and validation criteria on the property. If there are no modifiers besides the type (like string / number / boolean), validation is not generated. This is stuffed in prop.joiValidation, which will be used by the asset function generator later.
2. prop.data.validationFormat: We then eval() the joiValidation Calling it in the generator with eval(), calling describe() on the resulting Joi object and encoding that to JSON before putting it into package spec format.
3. Asset function: when generating the asset function for a prop with joiValidation, we add a setValidationFormat(<prop.joiValidation>) builder call to the PropBuilder, and prop.joiValidation is deleted to make sure we don't dump it unnecessarily into the PkgSpec we upload.

Testing

• Uploaded AWS::ECR::Repository locally and set RepositoryName to a single character. Watched validation go red.
• Did Regenerate Asset and updated said component. Validation still red!
