return concrete types!

[led0nk]

concrete/iface

Description:
As requested this PR removes the unnecessary use of

func (s *azureScraper) getArmClient() (armClient, error) 
func (s *azureScraper) getMetricsDefinitionsClient() (metricsDefinitionsClientInterface, error)
func (s *azureScraper) GetMetricsValuesClient() (metricsValuesClient, error)

Those methods returned interfaces which later got implemented by fields of the *azureScraper.
Now we directly assign them with their concrete types, which were handled through their interfaces before. The implementation of errorhandling was already done earlier.

IMO this is a separate issue / PR.

Otherwise, this PR looks great and cleans the code.
