/**
 * Create an instance of an ILP plugin
 *
 * This functions loads an instance of an ILP plugin.
 *
 * The constructor options and module name can be passed to the function as parameters.
 * If no parameters are provided then it willattempt to find the config in environment variables.
 * If these are not found it will load a plugin connected to a local moneyd instance on port 7768.
 *
 * The Environment variables that can be set are:
 *  - ILP_PLUGIN : The name/path of the plugin module
 *  - ILP_PLUGIN_OPTIONS : The options passed to the constructor, serialized as a JSON object.
 *
 * This function replaces the module 'ilp-plugin' which has been deprecated.
 *
 * Example 1: Explicit config
 *
 * ```js
 * const plugin = createPlugin({ "server" : "btp+ws://myname:0a0cfd180fb5a5d32ebdf5344ce9c076@localhost:7768" })
 * ```
 *
 * Example 2: Config from env
 *
 * ```sh
 *  $ ILP_PLUGIN="ilp-plugin-btp" \
 *    ILP_PLUGIN_OPTIONS="{\"server\":\"btp+ws://myname:0a0cfd180fb5a5d32ebdf5344ce9c076@localhost:7768\"}" \
 *    node app.js
 * ```
 *
 * Where `app.js` has the following:
 *
 * ```js
 * const plugin = createPlugin()
 * ```
 * @param {*} pluginOptions The options passed to the plugin constructor
 * @param {*} pluginModuleName The module name of the plugin, defaults to `ilp.DEFAULT_PLUGIN_MODULE`
