Closes #241 #255

Description of Changes

Each role data fields are record separately which is stored in role_data_record.
This role_data_record is difference from role_data_history where role_data_history store the whole role data at the specific point in time.

For example, for role 0,

Roledata at point 1222 {
     signing_key: X509_cert(A)
     encryption_key: None
    ......
}

Roledata at point 1322 {
     signing_key: Deleted X509_cert(A)
     encryption_key: C509_cert(B)
    ......
}

Roledata at point 1422 {
     signing_key: Undefined
     encryption_key: X509_cert(C)
    ......
}

Each entry of Roledata as shown above will be store in role_data_history

The role_data_record of role 0 will be

RoleDataRecord {
    signing_keys: [<1222, X509_cert(A)>, <1322, None>]
    encryption_keys: [<1322, C509_cert(B)>,  <1422, X509_cert(C)>]
    ....
}

• Note that key rotation is a record of any change to the key, so when key is deleted, it is also considered as rotation.

Breaking Changes

Renaming

• all_role_data -> role_data_history
