Fix json files

I accidentally tested pldm with a json linter and found a lot
of json issues in pldm, this commit would try to fix all of them.

The issues that are fixed in this commit are
1. As per nlohmann json, it only support // & /**/ for comments
   and those can be treated as spaces when we pass "true" for the
   skipcomments argument for the json::parse() function. Most of
   the places we used # for commenting.
2. RFC 7159 does not support hexadecimal numbers in json,so replacing
   it with its decimal equivalent.

3. This commit also adds the configuration files for eslint json linting
   as well the eslintignore configuration.
