KUDU-3448 Add support for encrypting TSKs

In a previous patch, support for encrypting IPKI root CA private keys
has been added. This is a follow up patch, to add encryption support for
token signing keys as well. It is controlled by a new flag:
--tsk_private_key_password_cmd.

If this flag is set, the token signing keys will be stored in the
syscatalog table in encrypted form (AES-256-CBC with PKCS#8 encoding).

Token signing keys rotate automatically in Kudu, but for now, at least,
encryption of TSKs can't be turned on or off on an existing master, so
if this flag is set on the first startup of a master, it must be set to
a command that outputs the same password as on initialization, and vice
versa, it must not be provided on later master startups if it wasn't
provided on initialization.
