URL Service redirect endpoint

[streamich]

Expose "redirect" endpoint which uses locators from the URL Service plugin to redirect users to a deep location within Kibana.

The endpoint could look as follows:

/app/r?l=<locator_id>&v=<version>&p=<params_json>

where

• locator_id — is the ID of a locator which should be used for the redirection.
• params — is a map of parameters that the specific locator receives.
• paramsVersion — the version of Kibana at which the parameter map was generated.

Tasks:

• Implement the redirect endpoint.
• Use parameter version to migrate the parameter map on-the-fly when request is being executed.
• Test coverage
• Mark it as for internal use.
• Add method to generate redirect URL.
