Adds Product Manager

[A-Guldborg]

Closes #7
Enables adding and updating products through the Shifty app.

Note, a couple things to be discussed:

• With the new endpoint in Adds GET products/all for privileged users analog-core#237 we can now see non-visible products and the property as well. We should figure out some styling / way to clearly indicate which products are not visible (i.e. likely disabled permanently). Right now, it is a gray-ish row on non-visible products, as well as a switch that indicates it is not visible when in edit mode.
• Having a dropdown of checkboxes for the user groups on a product contains an error: We are not able to override the custom text function in the dropdown in the edit form - likely because the editform itself is auto-generated. Now the solution instead is a checkbox for each usergroup but not in a dropdown. It is possible that we can add this to a dropdown list (but not a "select" object) and thus custom-implement the dropdown we want. But that is not very blazor-ish.

Please give inputs to the above discussion points and/or anything else :)

NB: Blocked until AnalogIO/analog-core#237 is merged as we require the endpoint created in that PR.

Almost done.

Few things:

1. I can't for the love of God format the text on the multi-select dropdown. Right now, when editing a produc,t, it shows only one value, e.g. "Customer", despite have both Customer and Board as user groups.
2. It seems the PR Allows setting product user groups analog-core#223 does not work as expected. It does not expose the product user groups in the API on a get request, but I believe that might just be one single line to be added in coffeecard\CoffeeCard.WebApi\Controllers\v2\ProductsController.cs in method MapProductToDto:

AllowedUserGroups = product.ProductUserGroup.Select(e => e.UserGroup)

(But I will need to test that before creating such a PR). Once at least the second issue mentioned here is fixed, this PR is ready for review)

The last two commits depends on new endpoint from AnalogIO/analog-core#237
(endpoint /api/v2/products/all)

Update: PR is merged.

I request all changes in #22 to be merged before continuing, which fixes the horizontal scrolling in the table.

And I renamed your PR :)

OK
