Fix missing key change in 20171124104327_migrate_kubernetes_service_to_new_clusters_architectures.rb

attr_encrypted does different things with `key` depending on what mode you are using:

1. In `:per_attribute_iv_and_salt` mode, it generates a hash with the salt:
https://github.com/attr-encrypted/encryptor/blob/c3a62c4a9e74686dd95e0548f9dc2a361fdc95d1/lib/encryptor.rb#L77.
There is no need to truncate the key to 32 bytes here.

2. In `:per_attribute_iv` mode, it sets the key directly to the password, so
truncation to 32 bytes is necessary.

Caching the attributes as JSON and manually instantiating the record
ended-up very complex since the edge-cases such as upload fields,
serialized fields, and fields with custom accessors had to be handled.

To ensure 3 points out of 4 are checked from https://gitlab.com/gitlab-org/gitlab-ce/issues/45175
we now include the Rails version in the cache key.
