the parallelism and parallelism-chunk-size flags
which used to control how many parts to split a
segment into and many to perform in parallel
are now deprecated and replaced by
maximum-concurrent-pieces and long-tail-margin.
now, for an individual transfer, the total number
of piece uploads that transfer will perform is
controlled by maximum-concurrent-pieces, and
segments within that transfer will automatically
be performed in parallel. so if you used to set
your parallelism to n, a good value for the pieces
might be something approximately like 130*n, and
the parallelism-chunk-size is unnecessary.

This change is similar to
https://review.dev.storj.io/c/storj/storj/+/7687 but applied when
uploading from stdin with parallelism > 1.
Currently, the paralellism from stdin scales up to 3 or 4, but not
greater than that. If we buffer the content from stdin more aggressively
the parallelism scales to higher levels and reaches the performance of
reading directly from a file.

This new advanced flag configures libuplink to store in-memory the
erasure-coded pieces that are temporarily created during upload.
By default, libuplink writes the erasure-coded pieces as temp files on
the disk, but this results in additional IOPS that affect the
performance in hot-rodded scenarios.
If the erasure-coded pieces are kept in-memory and the system has enough
RAM, the upload speed may be boosted with 20-30%.
The flag is added as "advanced" as we don't recommend it by default.

allow multiple source paths and a single destination path.
this makes commands like `uplink cp foo* sj://bucket` work
as expected.
require at least one remote path when copying. this ensures
that users don't accidentally overwrite their local files
with other local files, which is almost never what they wanted
because they would just use cp.

As a reminder: latest clingy removed the requirement of having custom context (which made the usage of context.WithValue harder) and uses simple context instead.
Clingy saves the stdin/stdout/stderr to the context (earlier to separated context type) to make it available for unit testing.

Current pipelining to stdout is synchronous so we don't have any
advantage from using --parallelism flag. This change adds buffer
while writing to stdout. Each part is first read into the buffer
and flushed only when all data was read from this part.

Main issue was that when one part copy failed while being inside
goroutine (limiter) and another part was still collecting src/dst parts
it was possible to drop errors from failed part copy. It was possible
bacause on fail context was canceled and if we were still getting
part src/dst then it was returning error immediately and error
group with errors from goroutine was ignored.

Few improvements were made to how we are handling errors
while doing parallel upload/download for single object:
* unhide error under 'context canceled' which was shown in most of
cases
* add part number to error message
* don't try to commit if any error occurs while operation
* combine errors into more readable form, example:

At some point uplink cli lost ability to set metadata. This change
brings back this functionality for 'cp' operation.

Uplink can upload from stdin and download to stdout. We had
such tests for old binary but now we were missing it.

This changes allows fetching the file size more easily (for supported
files) in order to afterwards calculate the multipart part size
accordingly.
Change-Id: Idabba4c2ee794ee471973889f5843174a7acad35
This change allows the uplink to bump the part size based on the
content length that is being copied. This ensures we are staying
below the 10k part limit currently enforced on the satellites.
If the user specifies the flag, it will error out if the value
chosen by the user is too low. Otherwise it will use it.

When ctx is cancelled limiter won't start a new goroutine.
The code didn't immediately return an error in that case.
The dst.Commit(ctx) would fail anyways due to a cancelled ctx.
However, we can make the behavior clearer by returning immediately.

Also ensure that abort is given at least 5 seconds to clear up any
pending uploads on cancellation.

If the cp command is executed with higher level of parallelism, it would
open more connections to storage nodes at the same time. Therefore, the
connection pool capacity should be expanded accordingly.
The pool capacity is set to 100 * parallelism.

I don't think it should matter for correctness whether this matches the
segment size or not, so I think there is something else wrong. However,
making this change seems to eliminate the "corruption when ulimit -n is
too low" problem we're seeing right now.

When copying an object from cli you can now set the expiry.
It uses the same datetime format as restricting access grants.
