[MNG-8476] discard "m2", use new repository directory name

**[Huang Xiao](https://issues.apache.org/jira/secure/ViewProfile.jspa?name=JIRAUSER305980)** opened **[MNG-8476](https://issues.apache.org/jira/browse/MNG-8476?redirect=false)** and commented

The ".m2" directory is located in the user's home directory:
* Windows: C:\Users\\.m2
* macOS/Linux: /Users/\/.m2 or /home/\/.m2

Maven 4.0 is about to be released ! It's time to discard ".m2" and use a new name, such as "maven".

The current mainstream version is maven3, and the use of "m2" is somewhat ambiguous. If the full name can be used in maven4 version, it will not only clearly express the meaning of the directory, but also have a better comparison with competitors (such as "gradle").

No source file or test is named. Start by locating Maven 4's handling of the user-home .m2 directory and the repository path, then trace all related documentation and compatibility behavior. Done means the new directory name is used consistently without leaving the requested repository behavior undefined.
