fix: logs updated on starting of a stopped container

[Shubhranshu153]

Issue:

When we start a container that was running and stopped or exited, logs are not updated.

Steps to Reproduce:

step 1: Run and exit container

sudo nerdctl run -it --name test-1 alpine:latest
/ # echo hello
hello
/ # exit

2. start the same container

 sudo nerdctl start -a test-1
/ # echo bar
bar
/ # exit

3. Check logs. Bar is missing.

 sudo nerdctl logs test-1
/ # echo hello
hello
/ # exit

fix:

The pr fixes it by adding multiwriters to start of containers.

Interactive Flag Added to start

Nerdctl didn't support interactive flag so added the flag to have compatible behavior with docker

@AkihiroSuda
PTAL when you get a chance.
Thank You.

Docker failure is #3908

Rootful failure is #3513

@Shubhranshu153 I just have a batch of nits on the test.

Btw, feedback on the test framework is highly welcome.

Ideally, if we get #3591 in first, we can get rid of the added DelayOnceReaders here (and unbuffer).

But anyhow, don't sweat it - I can clean that up afterwards if needed.

Needs rebase

this seems like an error regarding go mod jail? Not sure why go.mod is read during runtime.

It is (AkihiroSuda/gomodjail#50).

Gomodjail errors can be ignored for now.
