This test is non-representative of what we now do in libnetwork.
Since the ability of opening the same boltdb database multiple
times in parallel will be dropped in the next commit, just remove
this test.

The monitorDaemon() goroutine calls startContainerd() then blocks on
<-daemonWaitCh to wait for it to exit. The startContainerd() function
would (re)initialize the daemonWaitCh so a restarted containerd could be
waited on. This implementation was race-free because startContainerd()
would synchronously initialize the daemonWaitCh before returning. When
the call to start the managed containerd process was moved into the
waiter goroutine, the code to initialize the daemonWaitCh struct field
was also moved into the goroutine. This introduced a race condition.
Move the daemonWaitCh initialization to guarantee that it happens before
the startContainerd() call returns.

File paths can contain commas, particularly paths returned from
t.TempDir() in subtests which include commas in their names. There is
only one datastore provider and it only supports a single address, so
the only use of parsing the address is to break tests in mysterious
ways.

The bbolt library wants exclusive access to the boltdb file and uses
file locking to assure that is the case. The controller and each network
driver that needs persistent storage instantiates its own unique
datastore instance, backed by the same boltdb file. The boltdb kvstore
implementation works around multiple access to the same boltdb file by
aggressively closing the boltdb file between each transaction. This is
very inefficient. Have the controller pass its datastore instance into
the drivers and enable the PersistConnection option to disable closing
the boltdb between transactions.
Set data-dir in unit tests which instantiate libnetwork controllers so
they don't hang trying to lock the default boltdb database file.

The double quotes inside a single quoted string don't need to be
escaped.
Looks like different Powershell versions are treating this differently
and it started failing unexpectedly without any changes on our side.

- full diff: https://github.com/actions/setup-go/compare/v3.5.0...v5.0.0
v5
In scope of this release, we change Nodejs runtime from node16 to node20.
Moreover, we update some dependencies to the latest versions.
Besides, this release contains such changes as:
- Fix hosted tool cache usage on windows
- Improve documentation regarding dependencies caching
V4
The V4 edition of the action offers:
- Enabled caching by default
- The action will try to enable caching unless the cache input is explicitly
set to false.
Please see "Caching dependency files and build outputs" for more information:

errDrainDone is a sentinel error which is never supposed to escape the
package. Consequently, it needs to be filtered out of returns all over
the place, adding boilerplate. Forgetting to filter out these errors
would be a logic bug which the compiler would not help us catch. Replace
it with boolean multi-valued returns as they can't be accidentally
ignored or propagated.

While it doesn't really matter if the reader waits for an extra
arbitrary period beyond an arbitrary hardcoded timeout, it's also
trivial and cheap to implement, and nice to have.

The journald reader uses a timer to set an upper bound on how long to
wait for the final log message of a stopped container. However, the
timer channel is only received from in non-blocking select statements!
There isn't enough benefit of using a timer to offset the cost of having
to manage the timer resource. Setting a deadline and comparing the
current time is just as effective, without having to manage the
lifecycle of any runtime resources.
