Nova's keymgr implementation used to have default values for the algorithm and bit length. Castellan does not have default values, and when Castellan replaced keymgr in Ib563b0ea4b8b4bc1833bf52bf49a68546c384996, the parameters to the create_key method were not updated. This change parses the algorithm from the cipher value and passes it to Castellan's key manager interface. Closes-Bug: #1651887 Change-Id: Ib90bc7571aef59325be0efe123fcf12e86252b85
