> Host details page allows adding any uninstalled client component and some non-client
component to the host. 
> But there are some components that have a host scope dependencies on another components.
For example, Slider client won't function properly if HDFS client and YARN client are not
installed with it on the same host and thus slider client has host scope dependencies on HDFS
and YARN client. Such information is available from API.
> As a part of this ticket, ambari-web should maintain a map of host scope dependencies
for every component in StackServiceComponent model. 
> On host page while adding a component, ambari-web code should check if the component's
host scope dependencies are installed or not on that host. If not then show a single button
("OK") popup window informing the user to install them first:
> *popup window message:* 
> {code}"${ComponentNameTobeAdded} requires ${componentName},${componentName} and ${componentName}
to be installed along with it. Please add them first and then try adding ${{ComponentNameTobeAdded}"{code}
