Title: SHDP-287 Better app install/submit model

- Refactored built-in apps in spring-yarn-core handling
app lifecycles.
- New DefaultApplicationYarnClient which does a better job
installing and running apps by guarding against errors
by having a knowledge where app is installed and from
where app is started.
- New spring.yarn.applicationId which together with
applicationBaseDir can overwrite applicationDir. This
concept allows to install apps on a different hdfs
directories so that actual app dir can be resolved at runtime.
- YarnClientFactoryBean can know instantiate a yarn client based
on a given client class. Related changes in YarnClientConfigurer
and YarnClientBuilder.
