feat(logging): migration to structure logging for main.go, pkg/ & internal/ folders

…efactor configuration file

* Adds detection of booleans in string format to getNum.
* Refactors configuration file to allow definition of different metric types
  having different configuration variables.
* Refactor order of types and funcs in pkg/customersourcestate.
* Allows info and stateSet metrics to iterate over arrays.
* Adds `nilIsZero` config variable to gauge to indicate non-existing values to tread as 0 value instead of returning an error.
* Skip adding a label instead of setting value to `<nil>`.
* Replace namespace and subsystem by metricsNamePrefix
* Adjust docs for customresourcestate metrics to align with new configuration file

Represent GVK information as labels in the metrics, instead of appending
them to the metric name itself. This would allow users to aggregate
varying GVKs of a CR under the same metric, making operations much more
easier.

G104: Errors unhandled.

G112: Potential Slowloris Attack because ReadHeaderTimeout is not configured in the http.Server
G304: Potential file inclusion via variable
G601: Implicit memory aliasing in for loop.
