FALCON-2334 Tests in UpdateHelperTest suite fails with ParentNotDirectoryException
The UpdateHelperTest tests fails with the following error :
`Parent path is not a directory: /var/lib/jenkins/workspace/falcon/common/target/falcon/tmp-hadoop-jenkins/jail-fs/testCluster/projects/falcon/staging/falcon/workflows/process/sample`
The errors occurs only when the EntityUtilTest#testIsStagingPath test runs before the tests mentioned above.
The following code in EntityUtilTest#testIsStagingPath creates a file at path - target/falcon/tmp-hadoop-jenkins/jail-fs/testCluster/projects/falcon/staging/falcon/workflows/process/sample which causes the error :
```
if (createPath && !fs.exists(path)) {
fs.create(path);
}
```
The change proposed in this pull request deletes the files created in EntityUtilTest#testIsStagingPath after the test checks are done.

Closes #408 from sonia-garudi/FALCON-2334
Falcon is a feed processing and feed management system aimed at making it easier for end consumers to onboard their feed processing and feed management on hadoop clusters.
Dependencies across various data processing pipelines are not easy to establish. Gaps here typically leads to either incorrect/partial processing or expensive reprocessing. Repeated duplicate definition of a single feed multiple times can lead to inconsistencies / issues.
Input data may not arrive always on time and it is required to kick off the processing without waiting for all data to arrive and accommodate late data separately
Feed management services such as feed retention, replications across clusters, archival etc are tasks that are burdensome on individual pipeline owners and better offered as a service for all customers.
It should be easy to onboard new workflows/pipelines
Smoother integration with metastore/catalog
Provide notification to end customer based on availability of feed groups (logical group of related feeds, which are likely to be used together)
