Developer permissions for resources

[elfenpiff]

Brief feature description

When deploying iceoryx2 in a docker environment with inconsistent user setup, meaning that every docker container and the host are using a contradicting /etc/passwd, /etc/group then the default permissions prevent that a connection can be established between them.

To solve this, a flag development-permissions will be introduced. It will grant read-and-write access to every process, with the downside that this raises some security concerns since every process can modify the underlying resources. But this can be helpful during development when the permissions and final setup are not yet clear.

ToDo

• Add feature flag to rust and cargo
• Add dev_permissions flag to cmake
• Add dev_permissions flag to bazel
