Allows generators to ingest integers when type=number and format=float/double

Allows generators to ingest integers when type is number and format is float/double

• A new command line arg was added: --ints-allowed-for-float-double-formats which defaults to false
  • in the next major release (>=5.0.0) this default value will be set to true by default to automatically conform with json schema
• updated the 303 and 310 java and python clients to use that new generation option and sets it to true
• python updated to allow int + floats in when type = integer because json schema requires that ints are allowed in and that was a bug in the python implementation. The java implementation does not have this bug.

PR checklist

• Read the contribution guidelines.
• Pull Request title clearly describes the work in the pull request and Pull Request description provides details about how to validate the work. Missing information here may result in delayed response from the community.
• Run the following to build the project and update samples:

  mvn clean package 
  ./bin/generate-samples.sh
  ./bin/utils/export_docs_generators.sh
  

  Commit all changed files.
  This is important, as CI jobs will verify all generator outputs of your HEAD commit as it would merge with master.
  These must match the expectations made by your contribution.
  You may regenerate an individual generator by passing the relevant config(s) as an argument to the script, for example ./bin/generate-samples.sh bin/generate_samples_configs/python*
  For Windows users, please run the script in Git BASH.

Per json schema, int + float should be allowed in for int types. The values will be checked to ensure that they are integer like.
In the future a flag could be added floatingTypesAllowedForTypeInteger to disallow float here in python and Float/Double in java
The original code only allowing in int here is a bug.
