In these cases, continuing after a non nil error will result in a nil
dereference in panic.
Change the `assert.Check` to `assert.NilError` to avoid that.

This test was testing the client-side validation, so might as well
move it there, and validate that the client invalidates before
trying to make an API call.

Don't exit immediately (due to `set -e` bash behavior) when grep returns
with a non-zero exit code. Use empty dirs instead and let it print
messages about all tests being filtered out.

To avoid passing the `/` prefix in the -test.run to the integration test
suite, which for some reason executes all tests, but works fine with
integration-cli.

Previous check checked if ANY of the test directories isn't
integration-cli. This means it was true if TEST_FILTER matched multiple
tests from both integration and integration-cli suite.
Remove the grep `-v` inversion and replace it with a bash negation, so
it actually checks if there is no `integration-cli` in test dirs.

The mutex is only used on reads, but there's nothing protecting writes,
and it looks like nothing is mutating fields after creation, so let's
remove this altogether.

No context in the commit that added it, but PR discussion shows that
the API was mostly exploratory, and it was 8 Years go, so let's not
head in that direction :) b646784859

Now that we removed the interface, there's no need to cast the Network
to a NetworkInfo interface, so we can remove uses of the `Info()` method.

These errors aren't used in our repo and seem unused by the OSS
community (this was checked with Sourcegraph).
- ErrIpamInternalError has never been used
- ErrInvalidRequest is unused since moby/libnetwork@c85356efa
- ErrPoolNotFound has never been used
- ErrOverlapPool has never been used
- ErrNoAvailablePool has never been used

PR moby/moby#45759 is going to use the new `errors.Join` function to
return a list of validation errors.

Check the preferredPool first, as other checks could be doing more
(such as locking, or validating / parsing). Also adding a note, as
it's unclear why we're ignoring invalid pools here.
The "invalid" conditions was added in [libnetwork#1095][1], which
moved code to reduce os-specific dependencies in the ipam package,
but also introduced a types.IsIPNetValid() function, which considers
"0.0.0.0/0" invalid, and added it to the condition to return early.
Unfortunately review does not mention this change, so there's no
context why. Possibly this was done to prevent errors further down
the line (when checking for overlaps), but returning an error here
instead would likely have avoided that as well, so we can only guess.
To make this code slightly more transparent, this patch also inlines
the "types.IsIPNetValid" function, as it's not used anywhere else,
and inlining it makes it more visible.

This code was only run if no preferred pool was specified, however,
since [libnetwork#1162][2], the function would already return early
if a preferred pools was set (and the overlap check to be skipped),
so this was now just dead code.

This function intentionally holds a lock / lease on address-pools to
prevent trying the same pool repeatedly.
Let's try to make this logic slightly more transparent, and prevent
defining defers in a loop. Releasing all the pools in a singe defer
also allows us to get the network-name once, which prevents locking
and unlocking the network for each iteration.

Both functions have multiple output vars with generic types, which made
it hard to grasp what's what.

This makes it easier to consume, without first having to create an empty
PoolID.
Performance is the same:

BenchmarkPoolIDFromString-10 6252750 192.0 ns/op 112 B/op 3 allocs/op
Note that I opted not to change the return-type to a pointer, as that seems
to perform less;

As this function may be called repeatedly to convert to/from a string,
it may be worth optimizing it a bit. Adding a minimal Benchmark for
it as well.

Some tests were testing non-existing plugins, but therefore triggered
the retry-loop, which times out after 15-30 seconds. Add some options
to allow overriding this timeout during tests.
