This commit changes storagedriver.Filewriter interface
by adding context.Context as an argument to its Commit
func.
We pass the context appropriately where need be throughout
the distribution codebase to all the writers and tests.
S3 driver writer unfortunately must maintain the context
passed down to it from upstream so it contnues to
implement io.Writer and io.Closer interfaces which do not
allow accepting the context in any of their funcs.

go1.20.10 (released 2023-10-10) includes a security fix to the net/http package.
See the Go 1.20.10 milestone on our issue tracker for details:
https://github.com/golang/go/issues?q=milestone%3AGo1.20.10+label%3ACherryPickApproved

From the security mailing:
[security] Go 1.21.3 and Go 1.20.10 are released
Hello gophers,
We have just released Go versions 1.21.3 and 1.20.10, minor point releases.
These minor releases include 1 security fixes following the security policy:
- net/http: rapid stream resets can cause excessive work
A malicious HTTP/2 client which rapidly creates requests and
immediately resets them can cause excessive server resource consumption.
While the total number of requests is bounded to the
http2.Server.MaxConcurrentStreams setting, resetting an in-progress
request allows the attacker to create a new request while the existing
one is still executing.
HTTP/2 servers now bound the number of simultaneously executing
handler goroutines to the stream concurrency limit. New requests
arriving when at the limit (which can only happen after the client
has reset an existing, in-flight request) will be queued until a
handler exits. If the request queue grows too large, the server
will terminate the connection.
This issue is also fixed in golang.org/x/net/http2 v0.17.0,
for users manually configuring HTTP/2.
The default stream concurrency limit is 250 streams (requests)
per HTTP/2 connection. This value may be adjusted using the
golang.org/x/net/http2 package; see the Server.MaxConcurrentStreams
setting and the ConfigureServer function.
This is CVE-2023-39325 and Go issue https://go.dev/issue/63417.
This is also tracked by CVE-2023-44487.

go1.20.9 (released 2023-10-05) includes one security fixes to the cmd/go package,

[security] Go 1.21.2 and Go 1.20.9 are released
Hello gophers,
We have just released Go versions 1.21.2 and 1.20.9, minor point releases.
These minor releases include 1 security fixes following the security policy:
- cmd/go: line directives allows arbitrary execution during build
"//line" directives can be used to bypass the restrictions on "//go:cgo_"
directives, allowing blocked linker and compiler flags to be passed during
compliation. This can result in unexpected execution of arbitrary code when
running "go build". The line directive requires the absolute path of the file in
which the directive lives, which makes exploting this issue significantly more
complex.
This is CVE-2023-39323 and Go issue https://go.dev/issue/63211.

An incorrect alias snuck into 152af63ec5,
and DomainRegexp was aliased to the regex for digests (DigestRegexp).
This didn't affect this repository, as it didn't use the aliases and migrated
to the new module, but does affect user of the old module that depend on the
aliases.

Incorrect section indentation of the prometheus docs confuses some

This commit removes some `conn` parameters of private functions, which can
be obtain from the struct itself. The `conn` is for the old `redisgo` library,
which is replaced by `go-redis` in #4019.

In terms of results, a`manifestTagsPathSpec{ name: "repo" }` equals
`manifestTagPathSpec{ name: "repo", tag: "" }`, but from the intention,
the `manifestTagsPathSpec` should be used.

This commit cleans up and attempts to optimise the performance of image push in S3 driver.
There are 2 main changes:
* we refactor the S3 driver Writer where instead of using separate bytes
slices for ready and pending parts which get constantly appended data
into them causing unnecessary allocations we use optimised bytes
buffers; we make sure these are used efficiently when written to.
* we introduce a memory pool that is used for allocating the byte
buffers introduced above
These changes should alleviate high memory pressure on the push path to S3.
