Enable local volume mounts in func run for ConfigMaps, Secrets, EmptyDirs, and PVCs

[intojhanurag]

fix: #2940

Changes

• Updated pkg/docker/runner.go -> newHostConfig() to mount the following volume types:
  • ConfigMap → .func/run/configmaps/<name> directory
  • Secret → .func/run/secrets/<name> directory
  • EmptyDir → Docker tmpfs
  • PersistentVolumeClaim → .func/run/pvcs/<claimName> directory
• Added warnings for volumes that attempt to map outside of .func to prevent accidental access to sensitive host directories.
• Preserves existing behavior for port bindings and other container settings.

Hi @intojhanurag. Thanks for your PR.

I'm waiting for a github.com member to verify that this patch is reasonable to test. If it is, they should reply with /ok-to-test on its own line. Until that is done, I will not automatically test new commits in this PR, but the usual testing commands by org members will still work. Regular contributors should join the org to skip this step.

Once the patch is verified, the new status will be reflected by the ok-to-test label.

I understand the commands that are listed here.

hey @gauron99 , So what I can do for this ?

[gauron99]

I dont know, havent seen this error exactly. You can track it down and try to debug what happened. But some change you made in this code is causing that because it doesnt happen on main
