Check_MK Werk 7164: cmk-update-agent: Add timeout handling for connection to server

ID: 7164 Title: cmk-update-agent: Add timeout handling for connection to server Component: agents Level: 1 Class: Bug fix Version: 1.6.0i1 Previously, the connection from the agent updater to the Check_MK Server did not handle timeouts. This could lead to situations where the agent updater would run forever waiting for a response. This was particularly noticeable when running the agent updater under Windows, because the agent updater would fail to start over again, showing an error like <code>copying plugins\cmk-update-agent.exe to temp\cmk-update-agent.exe failed</code>. The agent updater now will cancel the connection if there is a connection timeout detected or if the connection freezes. The timeout limit is set to 120 seconds.<br> This timeout handling does not limit the overall connection time.
