This change allows a node to look for a piece in the trash when
serving a download request.
If the piece is found in the trash, it restores it to the blobs
directory and continue to serve the request as expected.

There are many case where the keywords `free` and `available`
are confused in their usage.
For most cases, `free` space is the amount of free space left
on the whole disk, and not just in allocation while
`available` space is the amount of free space left in the
allocated disk space.
What the user/sno wants to see is not the free space but the
available space. To the SNO, free space is the free space
left in the allocated disk space.
Because of this confusion, the multinode dashboard displays
the `free` disk space instead of the free space in the
allocated disk space https://github.com/storj/storj/issues/5248
While the storagenode dashboard shows the correct free space
in the allocation.
This change fixes the wrong free disk space. I also added a
few comments to make a distinction between the `free`
and `available` fields in the `DiskSpace*` structs.

Lazyfilewalker was failing with SIGPIPE which was quite
misleading. The command was failing because the
the value of the --lower-io-priority flag was assumed
to be an arguement since it was passed as
"--lower-io-priority true" instead "--lower-io-priority=true"

The execwrapper package wraps the exec.Cmd and has a Command
interface that mimics the behaviour of the exec.Cmd.
This is useful for testing the lazyfilewalker subprocesses
by stubbing instead of spawning a real subprocess.

As part of fixing the IO priority of filewalker related
processes such as the garbage collection and used-space
calculation, this change allows the initial used-space
calculation to run as a separate subprocess with lower
IO priority.
This can be enabled with the `--storage2.enable-lazy-filewalker`
config item. It falls back to the old behaviour when the
subprocess fails.

FileWalker implements methods to walk over pieces in
in a storage directory.
This is just a refactor to separate filewalker functions
from pieces.Store. This is needed to simplify the work
to create a separate filewalker subprocess and reduce the
number of config flags passed to the subprocess.

Calling stat() (really, lstat()) on every file during a directory walk
is the step that takes up the most time. Furthermore, not all directory
walk uses _need_ to have a stat done on every file. Therefore, in this
commit we avoid doing the stat at the lowest level of
walkNamespaceInPath. The stat will still be done when it is requested,
with the Stat() method on the blobInfo object.
The major upside of this is that we can avoid the stat call on most
files during a Retain operation. This should speed up garbage collection
considerably.
The major downside is that walkNamespaceInPath will no longer
automatically skip over directories that are named like blob files, or
blob files which are deleted between readdir() and stat(). Callers to
walkNamespaceInPath and its variants (WalkNamespace,
WalkSatellitePieces, etc) are now expected to handle these cases
individually.
Thanks to forum member Toyoo for the insight that this would speed up
garbage collection.

Starting restore trash in the background allows the satellite to
continue to the next storagenode without needing to wait until
completion.
Of course, this means the satellite doesn't get feedback whether it
succeeds successfully or not. This means that the restore-trash needs to
be executed several times.

The collector tries deleting a piece over and over again, though
the piece does not exist on the storagenode's filesystem.
We need to delete the piece info from the expired db if the
targeted file does not exist.
This does not resolve the base problem of why the file
is deleted before the collector tries deleting it.
This change deletes the piece info from the expired db
if the file does not exist, since we're already trying
to delete that piece anyway.

This is a temporary precaution to avoid incorrectly auditing nodes for pieces that were deleted between database backups if we have to restore from a previous backup.
Here we send pieces to trash rather than directly deleting them from storage nodes so we can restore from trash after a db restoration.

Sometimes SNOs fail to properly configure or lose connection to their storage directory
which can result in DQ. This causes unnecessary repair and is unfortunate for all parties.
This change introduces the creation of a special file in the storage directory at runtime
containing the node ID. While the storage node runs, it periodically verifies that it can
find said file with the correct contents in the correct location. If not, the node will
shut down with an error message.
This change will solve the issue of nodes losing access to the storage directory, but it will not
solve the issue of nodes pointing to the wrong directory, as the identifying file is created each
time the node starts up. After this change has been the minimum version for a few releases, we will
remove the creation of the directory-identifying file from the storage node run command and add it
to the setup command.
