Nopcommerce: Move away from KendoUI controls (not just a grid) or upgrade to the latest version

[AndreiMaz]

Right now we plan to move away from KendoUI grid because it's not included in the latest version of KendoUI - https://github.com/nopSolutions/nopCommerce/issues/75 (let's finish it first)

Once it's done we can:

1. Move away from KendoUI controls (find a new one). Hence we can completely remove KendoUI from nopCommerce
2. Upgrade KendoUI to the latest version (it doesn't include the gird). Please note that in this case third-party vendors who want to use KendoUI grid won't be able to continue its usage because we cannot use both versions of KendoUI (the current outdated one and the latest one)
3. Look at https://github.com/nopSolutions/nopCommerce/issues/30

Use Select2 (https://select2.org/) plugin for combobox instead of kendo ui dropdown.

What do you think about waiting for net core 3.0 and use razor components?

I think using Blazor (Razor + C#) will take time - it is scheduled to release in a few months...
