bug: added support for relative volume mounts in docker compose

[amoghumesh]

Related Issue

• When relative file paths are present in docker compose file of the application, application is mounted at /files to the keploy container so relative paths are resolved to the path inside keploy container but they should actually be resolved to host file system paths.

Closes: #1049

Describe the changes you've made

• Created three new functions in pkg/clients/docker/docker_client.go:

  • CheckBindMounts: Returns true if any relative paths are being used in volumes in compose file
  • ReplaceRelativePaths: Replaces relative paths with absolute path with respect to host filesystem which it obtains by calling GetHostWorkingDirectory. Creates a new kdocker-compose.yml file with the changes.
  • GetHostWorkingDirectory: Inspects keploy-v2 docker container and gets the mount path for /files. This is the application directory in the host file system.

• Added an if block in pkg/hooks/launcher.go which runs for docker compose related commands and checks if relative file paths are present and replaces them.
