HADOOP-19766: ABFS. Force Blob Instance for FNS Accounts

[manika137]

Description of PR

JIRA: https://issues.apache.org/jira/browse/HADOOP-19766
We have observed cases of ABFS driver being initialised with DFS for FNS accounts which is not a recommended endpoint by the service.
To prevent this, we’re normalizing endpoint to Blob for FNS accounts even if they were initialized with DFS endpoint. We also shall restrict usage of a separate ingress service type for FNS accounts.

How was this patch tested?

Test suite was run. Results of which are added in the comments below
