Remove reload option to wae initializer service

Reload option is not needed anymore.
To be secure, remove all KEKs from dek store (also adek) after loading
preloaded adeks once. Loaded adeks are stored in key-manager so they're
useless.
Related test cases are added. (load preloaded app deks)

(TODO) To use key-manager initial value feature is highly considered
to store KEK private key more securely.
