Added NetworkResurrector.Agent service
Upgrade all services to net5.0
NetworkResurrector.Agent is a service that will be installed on a host machine with the scope to execute operations like shutdown, restart, etc directly.
The system will be able to execute these operations in multiple ways. This is just the first one and all of them are handled by the NetworkResurrector.Api. For example, if the user wants to shutdown a clean Windows machine, he can use the agent and configure the API to call it, but in case of a proxmox machine, the API can be configured to execute a http request directly to the OS with the shutdown action (without the need for the agent).

NetworkResurrector.Agent improvements
• Multiple operations were implemented in the agent: Shutdown, Restart, Sleep, LockLogout and Cancel. The "Cancel" action can cancel one of the previously operations programmed with a delay.
• Added NetworkResurrector.Agent.Wrapper nuget package. It provides an easy and efficient method for a developer to connect another system written in .NET to this agent.
