🎩 What is the goal?

Add indicators to event screen

📝 How is it being implemented?

• I have added a new icon in toolbar and menu of event screen. This icon only is visible if the program of the event has program indicators.
• I have created a new DialogFragment, layout, presenter for indicators and Dagger classes Component and module
• I have used existed EventsRuleEngineRepository fixing a bug

The presenter is a copy from enrollment indicators presenter but using event repositories and without filter by enrollment.

For success build It's necessary to add this build gradle to dhis2-rule-engine:

apply plugin: 'java'

dependencies {
    testImplementation 'junit:junit:4.12'
    testImplementation group: 'org.assertj', name: 'assertj-core', version: '3.11.1'
    testImplementation group: 'org.mockito', name: 'mockito-all', version: '1.8.4'
    testImplementation "com.google.truth:truth:0.44"
    testImplementation group: 'nl.jqno.equalsverifier', name: 'equalsverifier', version: '3.1.9'

    implementation 'com.google.code.findbugs:jsr305:3.0.2'
    implementation 'com.google.guava:guava:24.1-android'
    compileOnly "com.google.auto.value:auto-value:1.5.2"
    annotationProcessor "com.google.auto.value:auto-value:1.5.2"
    implementation group: 'org.apache.commons', name: 'commons-lang3', version: '3.8.1'
    implementation group: 'commons-logging', name: 'commons-logging', version: '1.2'
    implementation group: 'org.apache.commons', name: 'commons-jexl', version: '2.1.1'
}

💥 How can it be tested?

Use case 1: - Navigate to events for the program 'Yaws - case register (Yaws/003)' and open an existed event then the indicators icon and menu should not be visible
Use case 2: - Navigate to events for the program 'BU02 - Register - With scoring' and open an existed event then the indicators icon and menu should be visible
Use case 3: - Create a new event and show indicators after answer questions, the indicators should be calculated
