WIP Software Carbon Intensity (SC) implementation

[mtthwcmpbll]

Work in Progress

This is an implementation of the SCI computation with providers for the different components of the calculation. It exposes a new actuator endpoint /actuator/carbon/sci that pulls energy consumed, marginal emissions, and emboddied emissions and produces the SCI score.

At the moment, the implementation providers are:

• a MarginalEmissionsProvider coming from the carbon-aware-sdk client already present in the project
• a EmboddiedEmissionsProvider that pulls from the application properties or defaults to 0.0 (to ignore emboddied emissions or assume the hardware is carbon neutral)
• an EnergyConsumptionProvider that provides a random value. This is intended to work towards a energy consumption value based on CPU+Memorry usage.

Looks good to me. Merging it
