This patch cuts down the size of directory trees used for
distcp contract tests against object stores, so making
them much faster against distant/slow stores.
On abfs, the test only runs with -Dscale (as was the case for s3a already),
and has the larger scale test timeout.
After every test case, the FileSystem IOStatistics are logged,
to provide information about what IO is taking place and
what it's performance is.
There are some test cases which upload files of 1+ MiB; you can
increase the size of the upload in the option
"scale.test.distcp.file.size.kb"
Set it to zero and the large file tests are skipped.

Introducing fs.azure.readahead.range parameter which can be set by the user.
Data will be populated in buffer for random reads as well which leads to fewer
remote calls.
This patch also changes the seek implementation to perform a lazy seek. The
actual seek is done when a read is initiated and data is not present in the buffer else
data is returned from the buffer thus reducing the number of remote storage calls.

When the S3A and ABFS filesystems are closed,
their IOStatistics are logged at debug in the log:
org.apache.hadoop.fs.statistics.IOStatisticsLogging
Set `fs.iostatistics.logging.level` to `info` for the statistics
to be logged at info. (also: `warn` or `error` for even higher
log levels).

The ABFS Filesystem and its input and output streams now implement
the IOStatisticSource interface and provide IOStatistics on
their interactions with Azure Storage.
This includes the min/max/mean durations of all REST API calls.

This moves the mock account name --which is required to never exist-- from
"mockAccount" to an account name containing a static UUID.

This defines what output streams and especially those which implement
Syncable are meant to do, and documents where implementations (HDFS; S3)
don't. With tests.
The file:// FileSystem now supports Syncable if an application calls
FileSystem.setWriteChecksum(false) before creating a file -checksumming
and Syncable.hsync() are incompatible.

The ABFS connector now implements listStatusIterator() with
asynchronous prefetching of the next page(s) of results.
For listing large directories this can provide tangible speedups.
If for any reason this needs to be disabled, set
fs.azure.enable.abfslistiterator to false.

DETAILS:
The previous commit for HADOOP-17397 was not the correct fix. DelegationSASGenerator.getDelegationSAS
should return sp=p for the set-permission and set-acl operations. The tests have also been updated as
follows:
1. When saoid and suoid are not specified, skoid must have an RBAC role assignment which grants
Microsoft.Storage/storageAccounts/blobServices/containers/blobs/modifyPermissions/action and sp=p
to set permissions or set ACL.
2. When saoid or suiod is specified, same as 1) but furthermore the saoid or suoid must be an owner of
the file or directory in order for the operation to succeed.
3. When saoid or suiod is specified, the ownership check is bypassed by also including 'o' (ownership)
in the SAS permission (for example, sp=op). Note that 'o' grants the saoid or suoid the ability to
change the file or directory owner to themself, and they can also change the owning group. Generally
speaking, if a trusted authorizer would like to give a user the ability to change the permissions or
ACL, then that user should be the file or directory owner.
