Add support for client/server or Similar mixed ipmitool

Use Case is:

• Proxmox VE Host (CPU Temperature Controller, SSD/NVME Boot Drives)
• Debian VM NAS (with LSI 9211-8i / 9207-8i PCIe Passthrough and several HDDs)

As such, the Control needs to be done in a Master-Slave Configuration most likely.
In the Most General Sense, it's a Master - N x Slaves Configuration.

• Host
  a. Global Temperature Controller: set Fan Speeds
  b. CPU(s) Temperature Controller
  c. SSD/NVME Boot Drives Temperature Controller
• Guest VM
  a. HDDs Temperature Controller
  b. HBA Temperature Controller ????

Essentially 2 Approaches are Possible:
a. Host does ALL the Control, Guest VM Communicates the Temperature Values
b. Split regulation as outlined above, Guest VM communicates the required Fan Speed

Probably a single Centralized Controller is easier.

In any Case, care shall be taken in case the Slave stops sending Temperatures/Fan Speed References, there shall be some kind of Interlocking (or "Default to 80% Fan Speed or something like that").

Examples that could be used for Implementation.

Flask HTTP API (most Flexible, Server just goes asking the Client for Values):

• https://auth0.com/blog/developing-restful-apis-with-python-and-flask/#-span-id--bootstrapping-flask----span--Bootstrapping-a-Flask-Application

Sockets Programming (probably limited to 1 Client & must do Splitting/Rebuilding of Strings Manually, compared to Flask API which simply Outputs JSON):
