[WIP] Add electron energy equation to hybrid solver

[marcoacc95]

This PR adds the following changes:

• temperature and entropy multifabs to fluid container
• creates an electron fluid container in the warpx class specifically for the hybrid solver
• adds a pressure calculation function that uses ideal gas expression instead of adiabatic formula
• Electron pressure calculation now reads Te from the multifab in the electron fluid container
• calculate Ue for electron fluid after ampere(plasma) current is computed
• Added functions to set Ke on grid and to update Te
• will use qdsmc from Topanga paper for EEES (see section III-A) in: https://doi.org/10.1063/5.0177132)
• Added a QdsmcParticleContainer similar to the FieldProbeParticleContainer. This container is needed for the qdsmc fictitious particles that advect the electron entropy and updates Te in absence of sources/sinks. This particle container contains the logic to initialize and push the qdsmc particles as well as gather properties from the grid (Ke, density) and deposit Ke after pushing the particles every step.
• Current implementation is nodal

Work in progress:

• current implementation is only for 3D simulations, extend to the rest of the dimensions the Hybrid solver can work with.

• Generalize DepositK to DepositScalarField for future extensions to the general qdsmc algorithm (neutral fluid)

• Move qdsmc particle container and electron fluid container to HybridPICModel object instead of WarpX class.

• Fluid container might be an overkill for this algorithm, might be useful to write separate QDSMC class that contains all the logic and can be extended in the future for neutral gases.
