Feature/added ipc flag

[sachinkum0009]

• Introduced a new IPC class that extends RockerExtension to handle IPC namespace options.
• Implemented get_name to return the 'ipc' identifier.
• Added get_docker_args method to generate Docker IPC arguments based on CLI input.
• Included a get_preamble method that returns an empty string as no preamble is needed.

This PR enables the use of IPC-related Docker arguments in Rocker configurations and should close the issue #241.
