Enforce project name length checking

[Yuanhui Liu]

Currently in Project create / update, there is no checking on the project name length. But once the form is submitted, the system actually checked the length of the project name and reported error on that, as shown below:

RESP BODY: {"error": {"message": "Project name should not be greater than 64 characters.", "code": 400, "title": "Bad Request"}}

It would be better checking this on the front end and display the specific error message.

    Restrict the length of the project name input

    There is an allowed maximum length for project name field, but in
    current code, it doesn't check or restrict that from UI side, i.e. user
    will be able to type in more than what is allowed. After form
    submission, it will fail but there is no clear message telling user what
    caused failure.

    After adding the code to restrict the max length of the project name
    field, user will not be able to input more than what is allowed, thus
    this error will be prevented from UI.
