 6   * Information on the Bootstrap stack of the environment we're deploying to.
 7   *
 8   * This class serves to:
 9   *
10   * - Inspect the bootstrap stack, and return various properties of it for successful
11   *   asset deployment (in case of legacy-synthesized stacks).
12   * - Validate the version of the target environment, and nothing else (in case of
13   *   default-synthesized stacks).
14   *
15   * An object of this type might represent a bootstrap stack that could not be found.
16   * This is not an issue unless any members are used that require the bootstrap stack
17   * to have been found, in which case an error is thrown (default-synthesized stacks
18   * should never run into this as they don't need information from the bootstrap
19   * stack, all information is already encoded into the Cloud Assembly Manifest).
20   *
21   * Nevertheless, an instance of this class exists to serve as a cache for SSM
22   * parameter lookups (otherwise, the "bootstrap stack version" parameter would
23   * need to be read repeatedly).
24   *
25   * Called "ToolkitInfo" for historical reasons.
