c6h12o6 86546f33ef Improve Full Packet parsing for HTTP (#1029)
This PR does two primary things: 
- ensures that HasFullPayload returns false if the packet doesnt start with a valid request or response header. This was necessary because a chunked response would return true from HasFullPayload if it got contiguous packets including the last packet (with the trailer) before it got the first packet (with the header).
- When the request payload is chunked across multiple packets, only correct for 100-Continue responses once. In requests with > 2 packets, the Ack number is incremented for each packet in the message, sometimes resulting in packets not being correlated with each other. This ensures that the message is corrected once and only once.

Leonid Bugaev d5c78155c9 Fix replay of files with malformed records (#1015)
In some cases recorded files contain small amount malformed records.
The root cause is not clear, maybe multiple processes writing to the same file.

This change ensuer that file can be replayed, and malformed records will be ingored (with meaningful debug message showing exact line in the file with issue).

Additionally `--input-file-dry-run` mode was speed up a bit, since there were a few of Sleep statements which were not ignored when dry run is executed.

This PR contains multiple fixes:
- Handle TCP padding (zeroes at the end of TCP payload), and do not treat it as a body
- Handle requests with "Expect: 100-Continue" - the ones which require confirmation from the server, before sending the body
- Fix muti-packet headers parsing, if "truncated" header starts with malformed header format
- Fix replay of pcap files (Ignore Stats method since it is not supported)
- Fix output file chunk size detection

Dima Golomozy 02a0904651 capture nics (#1000)
1. move the `isDevice(l.host, pi)` to be first, as no need to iterate on all nics if it returns `true`
2. first compare by name, as same nics will have same names
3. if not found by name, compare by ips.

the bug was the `strings.HasPrefix`
2 different nics with ipv6:
```
#nic1 ip: f1234::55
#nic2 ip: f1234::55::66::66
```

so because of the `strings.HasPrefix` it was evaluated as the name nics. but they are not.

# Native k8s integration
After following steps below, you will be able to capture traffic inside k8s like this:
```
gor --input-raw k8s://namespace/deployment/app:80 --output-http http://replay.com
```
GoReplay will running as a daemonset (e.g. on each phisical k8s node.
It will also require giving required permission to have read access to K8s APIs, so it can dynamically filter traffic for a specific pods.
Supported format for filtering required pods:
```
k8s://[namespace/]pod/[pod_name] - k8s://default/pod/nginx-7848d4b86f-5nxz8
k8s://[namespace/]deployment/[deployment_name] - k8s://default/deployment/nginx
k8s://[namespace/]daemonset/[daemonset_name] - k8s://default/daemonset/nginx
k8s://[namespace/]labelSelector/[selector] - k8s://default/labelSelector/app=nginx
k8s://[namespace/]fieldSelector/[selector] - k8s://default/fieldSelector/metadata.name=nginx-7848d4b86f-5nxz8
```
`namespace` is optional, omit to use all namespaces: `k8s://labelSelector/app=replay`
## 1. Create a namespace
`kubectl create namespace goreplay`
## 2. Create the Kubernetes service account in the namespace:
`kubectl create serviceaccount goreplay --namespace goreplay`
## 3. Create Cluster Role which gives read-only access to the pods:
`kubectl -n goreplay -f clusterrole.yaml apply`
```yaml
kind: ClusterRole
apiVersion: rbac.authorization.k8s.io/v1
metadata:
name: pod-reader
rules:
- apiGroups: [""]
resources: ["pods"]
verbs: ["get", "watch", "list"]
- apiGroups: [""]
resources: ["deployments"]
verbs: ["get", "watch", "list"]
- apiGroups: [""]
resources: ["daemonset"]
verbs: ["get", "watch", "list"]
```
## 4. Attach role to goreplay service account
`kubectl -n goreplay -f rolebinding.yaml apply`
```yaml
kind: ClusterRoleBinding
apiVersion: rbac.authorization.k8s.io/v1
metadata:
name: goreplay-reader-binding
subjects:
- kind: ServiceAccount
name: goreplay
namespace: goreplay
roleRef:
kind: ClusterRole
name: pod-reader
apiGroup: ""
```
## 5. Start goreplay daemonset
`kubectl -n goreplay -f goreplay.yaml apply`
In arguments, specify which service you want to capture.
Following format supported:
```yaml
apiVersion: apps/v1
kind: DaemonSet
metadata:
  name: goreplay-daemon
spec:
  template:
    spec:
hostNetwork: true
serviceAccountName: goreplay
      containers:
      - name: goreplay
        image: buger/goreplay:latest
command:
- "--input-raw k8s://deployments/nginx:80"
- "--output-stdout"
```
## 6. Create a simple http service (Optionally)
`kubectl -n default -f nginx.yaml apply`
```yaml
apiVersion: apps/v1
kind: Deployment
metadata:
name: nginx
labels:
app: nginx
spec:
replicas: 1
selector:
matchLabels:
app: nginx
template:
metadata:
labels:
app: nginx
spec:
containers:
- name: nginx
image: nginx
ports:

---
apiVersion: v1
kind: Service
metadata:
name: ngnix-service
spec:
selector:
app: nginx
type: NodePort
ports:
- protocol: TCP
port: 80
targetPort: 80
```
## 7. Verify installation
Find url for your service using `kubectl get svc` or `minikube service --url ngnix-service -n http`, and make a call to it.
Get GoReplay logs, and check if it capture traffic of your service.
`kubectl logs -n goreplay -l name=goreplay-daemon --all-containers`
