Project: allow connecting a project to a remote repository after it has been created

[stsewd]

• Several methods were moved from the ProjectBasicsForm class to the ProjectForm class, and UpdateProjectForm now inherits from ProjectForm. This was so we can use the default form field of the remote repository foreign key, while also sharing some code.

Closes #9437

I have been pushing to use verbose text for the default/initial widget text:

If a project has a connected repository, it should be selected in this dropdown, correct? If so, when there is no connected repository the dropdown initial value might be "No connected repository" instead of "-------".

yep, I'll change the text of the default empty selection.

It might also be worth using something like "Connected repository" instead of "Remote repository" in the user UI, to give a stronger framing to the user about the purpose of the field -- "remote repository" doesn't quite do this.

@stsewd Do the view changes affect the project creation views on either dashboard at all? I'm having trouble figuring this out by looking at the code.

Nope, that input is still hidden from the creation form.

A couple more notes. I think this is looking really good, I had a couple other comments on the PR that might change this a little bit.

This looks great!

After this as a first pass, I think we'll eventually want a polish pass on this that adds some more UI or maybe just moves the form view too. This is mostly to add a modal warning or something "Hey, don't change this if you're not sure exactly what this is doing".

But also, we talked about making this a nice UI too, so perhaps that's all one project and it all belongs in a dedicated admin UI.

Is it possible to make the field searchable in the new dashboard? (similar to what we do at "Add project"). Users with a lot of repositories will have issues finding the correct one.

It's searchable
