This change adds a GetRequiredPlugins RPC method to the language host, enabling us to query it for its list of plugin requirements. This is language-specific because it requires looking at the set of dependencies (e.g., package.json files). It also adds a call up front during any update/preview operation to compute the set of plugins and require that they are present. These plugins are populated in the cache and will be used for all subsequent plugin-related operations during the engine's activity. We now cache the language plugins, so that we may load them eagerly too, which we never did previously due to the fact that we needed to pass the monitor address at load time. This was a bit bizarre anyhow, since it's really the Run RPC function that needs this information. So, to enable caching and eager loading -- which we need in order to invoke GetRequiredPlugins -- the "phone home" monitor RPC address is passed at Run time. In a subsequent change, we will switch to faulting in the plugins that are missing -- rather than erroring -- in addition to supporting the `pulumi plugin install` CLI command.
