Add field validation

**Is your feature request related to a problem? Please describe.**
As part of validating user's responses, we would like to add field validation indicated in the property's JSON schema.

**Describe the solution you'd like**
We are able to validate for "urls". This is indicated using the `format: uri`. We would also like to support condition validation as denoted in the JSON schema through if-then keywords. Form.io already provides this functionality so it is just a matter of configuring the Form.io components based on the ingested schema.

**Describe alternatives you've considered**
We could write separate functions that perform validation upon form submission, however Form.io already provides this functionality out of the box.

**Additional context**
Helpful for fields such as `repositoryURL`, `usageType` & `exemptionText`, `maintenance` and `contractNumber`

该 issue 未指定文件、测试或入口点；首先定位摄取的 JSON schema 被转换为 Form.io 组件的位置。完成的标准是：schema 的 uri 格式和所述的 if-then 条件都体现在生成的表单中，包括列出的字段。
