Switching permission mode on not installed agent

[michalpristas]

Switching permission mode on not installed agent has not defined behavior.

While CLI allows to switch permission mode e.g from unprivileged to privileged what happens is:

• permission of files is changed
• running process keeps running
• service is installed referencing not existing files (standard install directory)
• service is not starting hence binary is not found

We should either

• disable commands for not installed agent (switch implementation states it support installed agents only)
• fix the behavior for not installed agents.

Disable! Because we are not running the daemon, it is on the user to exercise the binary correctly.
