evolve current support for languages on Cucumber/Gherkin

The current support for multi-language in Cucumber/Gherkin based Tests is incomplete and inconsistent.

What we have:

• there is a global setting that enforces the language whenever exporting feature files. This setting also allows to use the user's profile defined language 
  • https://confluence.xpand-it.com/display/XRAY/Miscellaneous#Miscellaneous-CucumberExportLanguage
• whenever exporting features (by the UI or the REST API), the "Feature" and "Scenario/Scenario Outline" keywords are being translated; the other Gherkin keywords no (e.g. Given, When, And, But, Then)
• the edition of Cucumber Tests/Backgrounds performs syntax highlighting and keywords validation, accordingly with the user profile's defined language 

What we could have:

• translate also the Gherkin keywords used in steps (e.g. Given, When, And, But, Then) to the destination language (could this be possible?!)
• ability to choose the export language (as an optional parameter), whenever using the REST API to export/generate cucumber features
