This PR adds support for HealthCheck, being able to supply, for example:
```yaml
version: "3"
services:
redis:
image: redis
healthcheck:
test: echo "hello world"
interval: 10s
timeout: 1s
retries: 5
```
Which is then converted to:
```yaml
spec:
containers:
- image: redis
livenessProbe:
exec:
command:
- echo "hello world"
failureThreshold: 5
periodSeconds: 10
timeoutSeconds: 1
name: redis
resources: {}
restartPolicy: Always
```
At the moment, this only supports livenessProbe, with support for readinessProbe in the future.
Adds support for deploy: mode.
For example:
```yaml
version: "3"
services:
foo:
deploy:
resources:
mode: global
replicas: 6
image: redis
```
Will only generate replicas: 1 in Kubernetes pods as "global" limits
replicas to only one.
This command will add `kompose command` used to generate artifacts as well as `kompose version`,
for ex,
```
metadata:
annotations:
kompose.cmd: kompose convert -f /home/snarwade --stdout
kompose.version: 1.0.0 (HEAD)
```
For functional test, Now each test has template like,
```
"annotations": {
"kompose.cmd": "%CMD%",
"kompose.version": "%VERSION%"
```
Because, for every machine these values will be different.
Updated functional test with new annotations
This does a major refactor on the compose.go functions as well as brings
in a new era of v3 support to Kompose.
Similar to how we utilize libcompose, we utilize docker/cli's "stack
deploy" code which has a built-in v3 parser. We convert the parsed
structure to our own and then convert it to Kubernetes/OpenShift
artifacts.
