Do not require package manager flag to work with named containers

[mks-h]

Currently, I have to write apx enter --dnf --name a_name to access a named container. Considering that --name option appends custom name to apx_managed_dnf, it could infer what package manager to use with the container, so that I can skip --dnf

[mks-h]

Unless the idea is to be able to name different containers the same name, which would be kinda confusing

Hi, I am closing this issue as package manager flags are no longer part of Apx v2. Instead, you directly specify the subsystem and its command. (i.e apx <subsystem> install <package>)
