feat: add dashboard for shared dependency version checking

[yangnuoyu]

Overview:
We intend to use google-cloud-shared-dependencies for all the libraries in the google-cloud-bom. To avoid dependency conflict, we want to make sure the versions of google-cloud-shared-dependencies in all the libraries are the same before we actually release the bom. So we try to build a dashboard for google-cloud-bom to show the version of google-cloud-shared-dependencies in the libraries of google-cloud-bom.

Goals:

1. Calculate the number of libraries in the google-cloud-bom and show them
2. Count the number of libraries where upper bounds errors occur
3. Count the number of libraries who fail to converge
4. Show the version of libraries in the bom and the latest version released in the Maven Center with release date.
5. Show the version of google-cloud-shared-dependencies in the library
6. Add link to the resources of data
7. Add build date of dashboard
8. Generate the result for released and snapshot of the google-cloud-bom
9. Deploy and run it at scheduled time
