Fetch End Device Template by numeric IDs

[KrishnaIyer]

Summary

Closes #4842

Changes

• Create a new index in bleve for the profiles.
• Extend the GetTemplate RPC to allow numeric IDs and get them.
• Update tests
• Remove the unused no-op implementation.

Testing

UT + local

Regressions

• The current GetTemplate function (which loads the template on the console) is tested and works as expected.

Notes for Reviewers

1. Afaik, none of the device profiles in the repository have a correct vendorProfileID. This field is either not present or filled with the same value for all devices for a brand. Until now this wasn't necessary, but for customers to use this PR properly, those need to be adjusted. cc @Jaime-Trinidad
