Add the ability to bundle multiple plugins into a meta plugin (#28022) This commit adds the ability to package multiple plugins in a single zip. The zip file for a meta plugin must contains the following structure: |____elasticsearch/ | |____ <plugin1> <-- The plugin files for plugin1 (the content of the elastisearch directory) | |____ <plugin2> <-- The plugin files for plugin2 | |____ meta-plugin-descriptor.properties <-- example contents below The meta plugin properties descriptor is mandatory and must contain the following properties: description: simple summary of the meta plugin. name: the meta plugin name The installation process installs each plugin in a sub-folder inside the meta plugin directory. The example above would create the following structure in the plugins directory: |_____ plugins | |____ <name_of_the_meta_plugin> | | |____ meta-plugin-descriptor.properties | | |____ <plugin1> | | |____ <plugin2> If the sub plugins contain a config or a bin directory, they are copied in a sub folder inside the meta plugin config/bin directory. |_____ config | |____ <name_of_the_meta_plugin> | | |____ <plugin1> | | |____ <plugin2> |_____ bin | |____ <name_of_the_meta_plugin> | | |____ <plugin1> | | |____ <plugin2> The sub-plugins are loaded at startup like normal plugins with the same restrictions; they have a separate class loader and a sub-plugin cannot have the same name than another plugin (or a sub-plugin inside another meta plugin).

`src/main/plugin-metadata` and it will be applied during unit tests as well.
Keep in mind that the Java security model is stack-based, and the additional
permissions will only be granted to the jars in your plugin, so you will have
write proper security code around operations requiring elevated privileges.
It is recommended to add a check to prevent unprivileged code (such as scripts)
from gaining escalated permissions. For example:
[source,java]
--------------------------------------------------
// ES permission you should check before doPrivileged() blocks
import org.elasticsearch.SpecialPermission;
SecurityManager sm = System.getSecurityManager();
if (sm != null) {
// unprivileged code such as scripts do not have SpecialPermission
sm.checkPermission(new SpecialPermission());
}
AccessController.doPrivileged(
// sensitive operation
);
--------------------------------------------------
[DOCS] http -> https, remove outdated plugin docs (#60380) (#60545) Plugin discovery documentation contained information about installing Elasticsearch 2.0 and installing an oracle JDK, both of which is no longer valid. While noticing that the instructions used cleartext HTTP to install packages, this commit replaces HTTPs links instead of HTTP where possible. In addition a few community links have been removed, as they do not seem to exist anymore. Co-authored-by: Alexander Reelsen <alexander@reelsen.net>
