Feature/tp refetch

[tcfdev]

This is a continuation of the work in (PR 6118) as defined in the (Refetch Blueprint). These changes allow Traffic Portal to take advantage of the changes to the Traffic Ops API and Invalidation Jobs.

The table listing invalidation jobs has been modified to show the TTL explicitly (rather than Parameters) and the create form has been modified to account for the new Invalidation Type field. Traffic Portal integration test was updated to account for these changes as well.

There was also a minor change cleaning up the roles that were defined in some tests that may have been conflicting (read-only user should be read-only).

Which Traffic Control components are affected by this PR?

• Traffic Portal

What is the best way to verify this PR?

Manually, to launch and run Traffic Ops and Traffic Portal. Navigate to the Invalidation Content page under the Tools menu in Traffic Portal. Note the Parameters column is now titled TTL (Hours) as well as the addition of the Invalidation Type.

Manually, create an Invalidation Request. Note the new required field for Invalidation Type, which defaults to REFRESH.

Repeat the same observation and test as above, however navigate to Delivery Services. Select a Delivery Service. In the upper right drop down menu More -> Manage Invalidation Requests. The difference here is that the table and create form are specific to this particular DS.

Automatic integration tests must pass.

FWIW, "Number of hours until the invalidation request expires" is not a an appropriate placeholder value for an input[type="number"].

From the MDN section on input labeling:

The placeholder should never be required to understand your forms. It is not a label, and should not be used as a substitute, because it isn't. The placeholder is used to provide a hint as to what an inputted value should look like, not an explanation or prompt.

So it's supposed to be an example input, and this looks more like a label. Traditionally we'd put that in the "helptext" tooltips for the input labels, though for all I care it could just be the entire label text content. The title attribute might also be appropriate, though whether or not any user would encounter that is very implementation-dependent (and since we use form[novalidate]s no non-screen-reading user would ever see them unless they decide to hover it in a Chromium or Gecko engine browser).
