[CARBONDATA-2714][Merge Index] Fixed block dataMap cache refresh issue
after creation of merge index file
Things handled as part of this PR
1. Fixed block dataMap cache refresh issue after creation of merge index
file
**Problem:**
Block DataMap cache not getting refreshed after creation of merge index
file due to which queries still look for index file and fail.
**Analysis:**
Merge index file creation involves modification of segment file. If a query
is executed without merge Index file creation then cache will be loaded. Once
merge Index file is created the index file entries will be removed from segment
file and merge index file entry will be added. In this process the cache is not
getting refreshed and the tableIdentifiers created still have the
mergeIndexFIleName as null.
**Fix:**
After updating table status file clear the dataMap cache for all
segmentId's on which dataMap is being created
