Description

Ambari Agent, as part of host checks, identifies conflicting "alternatives" settings and reports back inside the "last_agent_env" object.
UI is not surfacing this in Host Checks popup.
We should have a section called "Alternatives Issues" and list out the alternatives names.
For example:

 "last_agent_env" : {
      "stackFoldersAndFiles" : [
        ...
      ],
      "alternatives" : [
        {
          "name" : "zookeeper-conf",
          "target" : "/etc/zookeeper/conf.dist"
        },
        {
          "name" : "hadoop-conf",
          "target" : "/etc/hadoop/conf.dist"
        },
      ],
      "existingUsers" : [
        ....
      ],
      "existingRepos" : [
        ...
      ],
      ...

In the above case, we want to highlight the fact that hadoop-conf and zookeeper-conf have conflicts.
