[SPARK-19736][SQL] refreshByPath should clear all cached plans with the
specified path
## What changes were proposed in this pull request?
`Catalog.refreshByPath` can refresh the cache entry and the associated
metadata for all dataframes (if any), that contain the given data source path.
However, `CacheManager.invalidateCachedPath` doesn't clear all cached plans
with the specified path. It causes some strange behaviors reported in
SPARK-15678.
## How was this patch tested?
Jenkins tests.
