* KEYCLOAK-5298: Enable autoescaping in Freemarker
* Fix several of the failing tests.
* Fix broken tests in integration-deprecated
* Fix last failing test.
* 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.
Configure password blacklist folder for tests
* KEYCLOAK-5244 Configure jboss.server.data.dir for test servers
* KEYCLOAK-5244 Translate blacklisted message in base/login
* KEYCLOAK-5191 Don't attempt to send 401 when response is already committed
* KEYCLOAK-5191 Defend against configuration errors by preventing 2xx response after authentication failure
