Followup to the original HADOOP-18582.
Temporary path cleanup is re-enabled for -append jobs
as these will create temporary files when creating or overwriting files.

Even though DiskChecker.mkdirsWithExistsCheck() will create the directory tree,
it is only called *after* the enumeration of directories with available
space has completed.
Directories which don't exist are reported as having 0 space, therefore
the mkdirs code is never reached.
Adding a simple mkdirs() -without bothering to check the outcome-
ensures that if a dir has been deleted then it will be reconstructed
if possible. If it can't it will still have 0 bytes of space
reported and so be excluded from the allocation.

Expands on the comments in cluster config to tell people
they shouldn't be running a cluster without a private VLAN
in cloud, that Knox is good here, and unsecured clusters
without a VLAN are just computation-as-a-service to crypto miners

Changes method name of RPC.Builder#setnumReaders to setNumReaders()
The original method is still there, just marked deprecated.
It is the one which should be used when working with older branches.

When closing we need to wrap the flush() in a try .. finally, otherwise
when flush throws it will stop completion of the remainder of the
close activities and in particular the close of the underlying wrapped
stream object resulting in a resource leak.

- In the YARN-1345 remove of FINAL_SAVING was missed from RMAttemptBlock
- Same issue was present after YARN-1345 in YARN-4411
- YARN-4411 logic was applied in this commit for FINAL_SAVING
Addresses CVE-2021-37533, which *only* relates to FTP.
Applications not using the ftp:// filesystem, which, as
anyone who has used it will know is very minimal and
so rarely used, is not a critical part of the project.
Furthermore, the FTP-related issue is at worst information leakage
if someone connects to a malicious server.
This is a due diligence PR rather than an emergency fix.
