> During app creation, the slider client calls AgentUtils.getApplicationMetainfo() 3 times. Each time this function actually download the whole app package from HDFS. If the app package is big, this is rather inefficient.
> The 3 places are:
> 1) SliderClient.actionBuild() -> AgentClientProvider.validateInstanceDefinition()
> 2) AgentClientProvider.getApplicagionTags()
> 3) AgentClientProvider.validateInstanceDefinition()
> We should cache the metainfo object in AgentClientProvider.
