HTTPTrap check management to separate checkmgr from cgm. Goes with go-trapmetrics for handling collection and submission of metrics from applications.

• Client - required, an instance of the API Client
• CheckConfig - optional, pointer to a valid API Client Check Bundle. If it is used at all, some or none of the settings may be used, offering the most flexible method for configuring a check bundle to be created. Pass nil for the defaults. Defaults will be used to backfill any partial configuration used. (e.g. set the Target and all other settings will use defaults.)
• SubmissionURL - optional, explicit submission URL to use when sending metrics (e.g. a circonus-agent on the local host). If the destination is using TLS then a SubmitTLSConfig must be provided.
• SubmitTLSConfig - optional, pointer to a valid tls.Config for the submission target (e.g. the broker or an explicit submission URL using TLS).
• Logger - optional, something satisfying the Logger interface defined in this module.
• BrokerSelectTags - optional, when creating a check and the check configuraiton does not contain an explict broker, one will be selected. These tags provide a way to define which broker(s) should be evaluated.
• BrokerMaxResponseTiime - optional, duration defining in what time the broker must respond to a connection in order to be considered valid for selection when creating a new check.
• CheckSearchTags - optional, the module will first search for an existing check satisfying certain conditions (active, check type, check target). This setting provides a method for narrowing the search down more explicitly for checks created via other mechanisms.
• TraceMetrics - optional, the path where metric traces should be written. Each metric submission (raw JSON) will be written to a file in this location. If set to -, metrics will be written using Logger.Infof(). Infof is used so that regular debug messages and tracing can be controlled independently. For debugging purposes only.
