Add register_name to register parameters by in datasets

[samantha-ho]

This PR adds a register_name property and kwarg to the ParameterBase class. This property defaults to returning the Parameter full_name.

Additionally, this PR modifies the register_parameter and add_result methods in the Measurement context to use the register_name of the parameters rather than the full_name.

These changes are made to split how parameters are organized within an Instrument or Station from how they show up in datasets. This allows greater flexibility on both ends. Attaching a Parameter to an instrument, for example, does not have to change the name of the parameter in the dataset.

These changes have been implemented for ParameterBase and registration has been updated for ParameterWithSetpoints. MultiParameter and ArrayParameter setpoints registration has not been updated in this PR.

To do:

• Add docstrings and an example notebook
• Expand tests
• Add changelog file
