Checkmk Werk 10975: Support local files in Agent Bakery

ID: 10975 Title: Support local files in Agent Bakery Component: agents Level: 2 Class: New feature Version: 1.7.0i1 The agent bakery now recognizes files placed under the local hierachy of the Checkmk site and packages them as a replacement for the corresponding non-local/builtin-files. Previously, this feature was available for some files like "custom-files" or the agent itself. Now this holds true for all files that get packaged into the baked agent package. For example, if you want to replace a plugin file, that is located at <code>~/share/check_mk/agents/plugins/my_plugin</code>, you would place your own version at <code>~/local/share/check_mk/agents/plugins/my_plugin</code>. Additionally, the agent bakery watches all files that are relevant for a package and will invalidate the current package upon changes in file size, modification date, or file permissions, resulting in a newly baked package with new agent hash on bake request. This is visible by an orange-colored "Bake agents" button at the agent bakery. Especially, if a file is added to the local hierarchy as a replacement for a builtin-file, this will be recognized as a file change and result in a new package on bake request. Please note: Some files will get renamed by the bake process, e.g. the source file <code>check_mk_agent.linux</code> will result in <code>check_mk_agent</code> in the final agent package. In order to get a local file packaged, you always have to place your local file using the source name (Here: <code>~/local/share/check_mk/agents/check_mk_agent.linux</code>).
