HADOOP-18802. Collision of config key name fs.viewfs.mounttable.default.name.key to other keys that specify the entry point to mount tables

[teamconfx]

Description of PR

https://issues.apache.org/jira/browse/HADOOP-18802

This PR changes the name of the previous fs.viewfs.mounttable.default.name.key to fs.viewfs.mounttable.default-name-key to avoid collision.
I also grepped for the parameter name and changed it in all places.

How was this patch tested?

(1) set fs.viewfs.mounttable.default-name-key to default
(2) run org.apache.hadoop.fs.viewfs.TestFcMainOperationsLocalFs#testGlobStatusWithMultipleWildCardMatches
the test passes.

For code changes:

• Does the title or this PR starts with the corresponding JIRA issue id (e.g. 'HADOOP-17799. Your PR title ...')?
• Object storage: have the integration tests been executed and the endpoint declared according to the connector-specific documentation?
• If adding new dependencies to the code, are these dependencies licensed in a way that is compatible for inclusion under ASF 2.0?
• If applicable, have you updated the LICENSE, LICENSE-binary, NOTICE-binary files?
