for very large machines (>10Gbit) it is still useful
to have parallelism for uploads because we're actually
bound by getting new pieces from the satellite, so doing
that in parallel provides a big win.
this change adds back that flag to exist for uploads, and
removes the backwards compatibility code for the flag with
the maximum-concurrent-pieces as they are now independent.
the upload code parallelism story is now this:
- each object is a transfer
- each transfer happens in N parts (size dynamically
chosen to avoid having >10000 parts)
- each part can happen in parallel up to the limit
specified
- each parallel part can have up to the limit of
max concurrent pieces and segments
this change also changes some defaults to be better.
- the connection pool capacity now takes into acount
transfers, parallelism and max concurrent pieces
- the default smallest part size is 1GiB to allow the
new upload code path to upload multiple segments

downloads still need the old copy code because they aren't
parallel in the same way uploads are. revert all the code
that removed the parallel copy, only use the non-parallel
copy for uploads, and add back the parallelism and chunk
size flags and have them set the maximum concurrent pieces
flags to values based on each other when only one is set
for backwards compatibility.

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.

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.

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 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.

recursive copy had a bug with relative local paths.
this fixes that bug and changes the test framework
to use more of the code that actually runs in uplink
and only mocks out the direct interaction with the
operating system.

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