Checkmk Werk 12646: agent_azure: correct piggyback-section headers

ID: 12646 Title: agent_azure: correct piggyback-section headers Component: Checks & agents Level: 1 Class: Bug fix Version: 2.1.0i1 Since version 2.0.0i2 the piggyback section header names have been post-processed (dash was replaced with an underscore). This could lead to the piggyback data no longer matching the configured CMK hosts. This fix removes the postprocessing for piggyback section headers.
