Endpoint context

Created a wazuh key with the next methods:

• logger: Kibana server logger
• security: instance to the current security platform.
• plugins: access to plugins
• api: contains a client to do request to Wazuh API. It's a wrapper of ApiInterceptor.

These are availables in the context param of endpoint handlers.
context.wazuh

api

It contains a client to do requests to Wazuh API endpoints as the internal user configurated for each host in the wazuh.yml or use the current user.

// Internal user
context.wazuh.api.client.asInternalUser.authenticate(apiIHostID: string)
context.wazuh.api.client.asInternalUser.request(method: string, path: string, data: any, options: {apiHostID: string})

// Current user
context.wazuh.api.client.asCurrentUser.authenticate(apiIHostID: string, authContext: any)
context.wazuh.api.client.asCurrentUser.request(method: string, path: string, data: any, options: {apiHostID: string})
