Choose smallest/cheapest instance as the default one

[floreks]

What this PR does / why we need it:

• Updated providers logic in the wizard to choose the smallest/cheapest instance by default
• Updated display name format to show all information after selecting an instance
• Fixed an issue with triggering refresh of sizes and related endpoints when datacenters are refreshed

Release note:

Cheapest/smallest provider instance will be chosen by default in the wizard
