> CompatibleRepositoryVersion ResourceProvider will have one more field called "upgrade_types"
that will be a list of all of the upgrade types that are supported from the current stack
to the target stack of the repo version that is registered.
> E.g.,
> * Current stack is 2.1
> * Cluster Version record for HDP 2.3 is INSTALLED (and has  repo)
> Then the button for Perform Upgrade should check the compatible repositories endpoint
for 2.1->2.3. That particular path will only allow NON_ROLLING (aka Express Upgrade).
> The API to use in order to determine whether ROLLING, NON_ROLLING (Express) or BOTH are
applicable is like this :
> Example : In order to check for 2.2 - > 2.3 upgrade, look at upgrade_types information
in order to determine the supported type.

> "href" : "http://c6401.ambari.apache.org:8080/api/v1/stacks/HDP/versions/2.2/compatible_repository_versions/2",
> "CompatibleRepositoryVersions" :
> { "display_name" : "HDP-2.3.0.0-2557", "id" : 2, "repository_version" : "2.3.0.0-2557",
"stack_name" : "HDP", "stack_version" : "2.3", * 
> "upgrade_types" : [ "ROLLING", "NON_ROLLING" ]* }
