DAST Site profile MVC Implementation
<!-- The first four sections: "Problem to solve", "Intended users", "User experience goal", and "Proposal", are strongly recommended, while the rest of the sections can be filled out during the problem validation or breakdown phase. However, keep in mind that providing complete and relevant information early helps our product team validate the problem and start working on a solution. -->
### Problem to solve
<!-- What problem do we solve? Try to define the who/what/why of the opportunity as a user story. For example, "As a (who), I want (what), so I can (why/value)." -->
As a DAST user, I want to be able to create a Site profile to use in my on-demand scans, so that I can have multiple saved sites to use from when running a scan.
### Intended users
<!-- Who will use this feature? If known, include any of the following: types of users (e.g. Developer), personas, or specific company roles (e.g. Release Manager). It's okay to write "Unknown" and fill this field in later.

### User experience goal
<!-- What is the single user experience workflow this problem addresses?
For example, "The user should be able to use the UI/API/.gitlab-ci.yml with GitLab to <perform a specific task>"
https://about.gitlab.com/handbook/engineering/ux/ux-research-training/user-story-mapping/ -->
The user should be able to create a site profile that contains a profile name and target URL.
### Proposal
<!-- How are we going to solve the problem? Try to include the user journey! https://about.gitlab.com/handbook/journeys/#user-journey -->
User needs to create profiles before they create on-demand scans:
Initial 13.2 scope:
1. Name input
1. URL input

Post-13.2:
After 13.2 the ability to edit profiles and additional fields will be supported. Review the additional scope in the design:
- Design details: [Figma file](https://www.figma.com/file/7CaJqOTOpPEOzkYkoU5bs5/DAST-Ondemand-Profile?node-id=172%3A20537)
### Permissions and Security
<!-- What permissions are required to perform the described actions? Are they consistent with the existing permissions as documented for users, groups, and projects as appropriate? Is the proposed behavior consistent between the UI, API, and other access methods (e.g. email replies)?-->
Maintainer, owner, and developer roles should have access to create new Site profiles.

### Documentation
<!-- See the Feature Change Documentation Workflow https://docs.gitlab.com/ee/development/documentation/workflow.html#for-a-product-change
* Add all known Documentation Requirements in this section. See https://docs.gitlab.com/ee/development/documentation/feature-change-workflow.html#documentation-requirements
* If this feature requires changing permissions, update the permissions document. See https://docs.gitlab.com/ee/user/permissions.html -->
The [DAST config docs](https://docs.gitlab.com/ee/user/application_security/dast/#configuration) should be updated to include creating new Site profiles.
