Hello
I have some troubles with event-broker module when setting up multi-site gerrit plugin.

I tried to put event-broker.jar to modules folder, lib folder, plugins folder, plugins folder with link into lib folder, lib folder with link into plugins folder, but nothing helped me.

Versions:
gerrit 3.4
multi-site 3.3.0
event-broker 3.4.0

multi-site.config
```
[index]
maxTries = 50
retryInterval = 30000

[broker]
bootstrapServers = kafka:9092
securityProtocol = PLAINTEXT
indexEventTopic = gerrit_index
batchIndexEventTopic = gerrit_batch_index
streamEventTopic = gerrit_stream
projectListEventTopic = gerrit_list_project
cacheEventTopic = gerrit_cache_eviction

[kafka "subscriber"]
enabled = true
pollingIntervalMs = 1000
KafkaProp-enableAutoCommit = true
KafkaProp-autoCommitIntervalMs = 1000
KafkaProp-autoOffsetReset = latest

[kafka "publisher"]
enabled = true

[ref-database "zookeeper"]
connectString = zookeeper:2181
```
part of gerrit.config
```
[gerrit]
...
installDbModule = com.googlesource.gerrit.plugins.multisite.GitModule
installModule = com.googlesource.gerrit.plugins.multisite.Module
instanceId = 123-123-123-123

[database]
type = h2
database = /home/jenkins/gerrit_agent/db/ReviewDB

[noteDb "changes"]
autoMigrate = true
disableReviewDb = true
primaryStorage = note db
read = true
sequence = trut
write = true
```
Error says:
