Update log fields
This MR contains several minor improvements for the log fields:
- adds the
namespace
field torouter
logs (currently missing) - record the user agent for
audit
logs: this should help us to identify if an action was performed from the Webservices portal, the OKD console or from the CLI) - change the
namespace_name
field incontainer
logs tonamespace
: this standardizes with the rest of the logs, allowing us to field all logs of a namespace with a single query (i.e. when searching fornamespace: my-app
we can immediately seeevent
,audit
,router
andcontainer
logs.
