Add missing translations for OTP authenticator settings and update
outdated translations for OTP authenticator
Fix minor issue for the username property (plural -> singular)
Add missing translations
* KEYCLOAK-6618: Include review feedback into German translations
* KEYCLOAK-6618: Reword translation for multi-factor authentication and fix minor translation issues
* KEYCLOAK-6618: Update German translation for the login theme
Message bundle keys have been reordered to be in sync with the english
version to improve scanning through the message bundles side-by-side.
The updated German translations from the account theme were applied to
the login theme as well (where applicable).
* KEYCLOAK-5244 Add BlacklistPasswordPolicyProvider
This introduces a new PasswordPolicy which can refer to
a named predefined password-blacklist to avoid users
choosing too easy to guess passwords.
The BlacklistPasswordPolicyProvider supports built-in as
well as custom blacklists.
built-in blacklists use the form `default/filename`
and custom ones `custom/filename`, where filename
is the name of the found blacklist-filename.
I'd propose to use some of the freely available password blacklists
from the [SecLists](https://github.com/danielmiessler/SecLists/tree/master/Passwords) project.
For testing purposes one can download the password blacklist
```
wget -O 10_million_password_list_top_1000000.txt https://github.com/danielmiessler/SecLists/blob/master/Passwords/10_million_password_list_top_1000000.txt?raw=true
```
to /data/keycloak/blacklists/
Custom password policies can be configured with the SPI
configuration mechanism via jboss-cli:
```
/subsystem=keycloak-server/spi=password-policy:add()
/subsystem=keycloak-server/spi=password-policy/provider=passwordBlacklist:add(enabled=true)
/subsystem=keycloak-server/spi=password-policy/provider=passwordBlacklist:write-attribute(name=properties.blacklistsFolderUri, value=file:///data/keycloak/blacklists/)
```
Password blacklist is stored in a TreeSet.
* KEYCLOAK-5244 Encode PasswordBlacklist as a BloomFilter
We now use a dynamically sized BloomFilter with a
false positive probability of 1% as a backing store
for PasswordBlacklists.
BloomFilter implementation is provided by google-guava
which is available in wildfly.
Password blacklist files are now resolved against
the ${jboss.server.data.dir}/password-blacklists.
This can be overridden via system property, or SPI config.
See JavaDoc of BlacklistPasswordPolicyProviderFactory for details.
Revised implementation to be more extensible, e.g. it could be
possible to use other stores like databases etc.
Moved FileSystem specific methods to FileBasesPasswordBlacklistPolicy.
The PasswordBlacklistProvider uses the guava version 20.0
shipped with wildfly. Unfortunately the arquillian testsuite
transitively depends on guava 23.0 via the selenium-3.5.1
dependency. Hence we need to use version 23.0 for tests but 20.0
for the policy provider to avoid NoClassDefFoundErrors in the
server-dist.
