Upgrading axios to 0.28 causes httpRequest to not filter out properties with null/undefined values

[pavinduLakshan]

Describe the issue:

$subject.

This breaks existing usage of httpRequest and httpRequestAll which might have been used with the assumption that axios will filter out the properties with falsy values.

In order to update axios, we need to update the httpRequest and httpRequestAll functions with an option to enable/disable stripping out properties with falsy values.

How to reproduce:

Update axios version to 0.28.0 in spa-sdk

Expected behavior:

Should be able to upgrade axios sdk without SDK functionality being broken.
