feat!: add dynamic cell and connection parameters for nest simulations.

[drodarie]

Describe the work done

• Add parameters attribute for NEST cell models and connection models. These are computed when the adapter is loading the simulation
• Rename nest_parameter type to nest_constant to match naming convention.
• Move common resolution attribute from subclasses into the bsb-core Simulation class

List which issues this resolves:

closes #215

Tasks

• Added tests
• Updated documentation

@Helveg I implemented a first draft version of a refactor for the nest simulation that introduce dynamic simulation parameters. See #215
Can I have your feedback on it? I am not sure if my implementation is correct.
Also I am not sure of what to do with the old class Parameter of bsb-core that seems to be used only in bsb-neuron...
