#716 Add additional headers and request mode header for HTTP action

[Tush-r]

Issue:

#716

Changes:

• Add addtionalHeaders string( JSON) field for HTTP action.
• Add noCorsMode checkbox field for HTTP action.
• Hide HTTP Content Type header field.
• Hide HTTP Accept Header field.
• Additional headers override all existing headers. This inclues current HTTP Content Type, HTTP Accept Header and, Authorization header in case of HTTP Authentication User and HTTP Authentication Password.

Description:

Add additionalHeaders field for HTTP action which takes a JSON string. Primary reason is to add support for additional authentication types. This change also adds UI for no-cors request type. Hide the existing Content-Type and Accept( in case of live action) headers, while preserving the current values.

TODO:

• Add a migration to GridActionHTTP.js model in future, to merge hidden headers into the new additionalHeaders field.
