Add node and parameter information to doctor report.

[fujitatomoya]

Description

Currently Node and Parameter information is just missing from the ros2doctor report.
Since those information is also important to know the ROS 2 system configuration, it would be nice to add those information as well as endpoints.

Motivation

Providing more information for ros2doctor report can be useful to understand the entire ROS 2 network.

@fujitatomoya hi, I would like to work on this.

I was testing how to implement this and this is my approach:

ros2doctor.checks: NodeCheck = ros2doctor.api.node:NodeCheck
ros2doctor.checks: ParameterCheck = ros2doctor.api.parameter:ParameterCheck

ros2doctor.report: NodeReport = ros2doctor.api.node:NodeReport
ros2doctor.report: ParameterReport = ros2doctor.api.parameter:ParameterReport

implementing the above entry points so that we can show info for node list and parameter list.

If its acceptable, I would like this to be assigned to me
