releases: support enterprise versions (#148)

* releases: support enterprise versions

* releases: refactor enterprise options into struct

* fix: readme spelling/grammar

* releases: support enterprise options for ExactVersion and Versions

* releases: require enterprise license installation

* releases: e2e test for enterprise installation

* releases: example of installing enterprise versions

* releases: add missing copywrite header

* installer: fix failing windows test

* simplify destination path conditional

* releases: make EnterpriseOptions a pointer instead

* fix error messages

* refactoring: reduce nil checks

* releases: revert to copying EnterpriseOptions

I'm not entirely sure this is actually necessary or beneficial (from memory consumption perspective) but I'm keeping it as-is as it should do no harm to existing users who do not install enterprise products.

  - `releases.{LatestVersion,ExactVersion}` - Downloads, verifies & installs any known product from `releases.hashicorp.com`
    - **Pros:**
      - Fast and reliable way of obtaining any pre-built version of any product
+     - Allows installation of enterprise versions
    - **Cons:**
-     - Installation may consume some bandwith, disk space and a little time
+     - Installation may consume some bandwidth, disk space and a little time
      - Potentially less stable builds (see `checkpoint` below)
  - `checkpoint.LatestVersion` - Downloads, verifies & installs any known product available in HashiCorp Checkpoint
    - **Pros:**
      - Checkpoint typically contains only product versions considered stable
    - **Cons:**
-     - Installation may consume some bandwith, disk space and a little time
-     - Currently doesn't allow installation of a old versions (see `releases` above)
+     - Installation may consume some bandwidth, disk space and a little time
+     - Currently doesn't allow installation of old versions or enterprise versions (see `releases` above)
  - `build.GitRevision` - Clones raw source code and builds the product from it
    - **Pros:**
      - Useful for catching bugs and incompatibilities as early as possible (prior to product release).
