Consider automatically generating "new package" template

[mjcarroll]

Maybe better suited to https://github.com/ros-infrastructure/rosdistro-reviewer

When a new package is added to an existing distribution, reviewers populate a template like:

- [ ] At least one of the following must be present
  - [ ] Top level license file:
  - [ ] Per package license files:
- [ ] License is [OSI-approved](https://opensource.org/licenses):
- [ ] License correctly listed in package.xmls
- [ ] Public source repo:
- [ ] Source repository contains ROS packages
- [ ] Each package meets [REP-144](https://www.ros.org/reps/rep-0144.html) naming conventions

<details><summary>Package name details</summary>
$ find . -name "package.xml" -exec grep --color=auto -e "<name>" "{}" ";"
<OUTPUT HERE>
</details>

<details><summary>License details</summary>
$ find . -name "package.xml" -exec grep --color=auto -e "<license>" "{}" "+"
<OUTPUT HERE>
</details>

We should automate this.
