EMS: Control Service: Added 'jwt' parameter for passing JWT token, in EMS server (NOT SECURE PRACTICE)

EMS: Web Admin: Improved the SSH console dialog: added 'Open in a new tab' button, replaced the webssh target DOM node to an iframe (better than 'object' as it was before), renamed occurrences of 'websshProxyUrl' to 'websshServiceUrl'

EMS: Control Service: Added method 'addMetricsFromEnvVars()' in 'InfoServiceController' class for including environment variables with configured prefixes in 'metrics' map sent to Web Admin. Added 'envVarPrefixes' property in ControlServiceProperties for setting the env. var. prefixes.

EMS: Web Admin: Added an 'Open in a new tab' link in SSH console (useful for debugging, but not only)

EMS: Web Admin: Modified 'admin-2-topology.vue' to update LeafletJS map with the (broker) connections between EMS server and resource-limited nodes without an aggregator responsible for collecting their metrics.

EMS: Web Admin: Fixed a colouring error in Topology Tree (Candidate nodes are now coloured cyan as in the LeafletJS map). Fix legend in LeafletJS map (Initializing or Non-clustered).

EMS: Control Service, pom.xml: Changed profile 'dev-docker-image-build' in 'control-service/pom.xml', to get activated when file '.dev-local-docker-image-build' exists at top-level EMS folder (not in control-service folder). Changed profile '.dev-skip-build-web-admin' in top-level 'pom.xml' to get activated when when file '.dev-skip-build-web-admin' does *NOT* exist in top-level EMS folder.

EMS: Control Service, Baguette Client Install: Changed JRE8 installation instruction set to download JRE8 from EMS server. Fixed instruction set placeholder processing to trim the ending '/' from BASE_URL and DOWNLOAD_URL variables.

EMS: Control Service: Improved profile 'dev-docker-image-build' in pom.xml, to get activated when file 'control-service/.dev-local-docker-image-build' exists.

EMS: Control Service: Added new profile 'dev-docker-image-build' in 'pom.xml' used for local docker image builds. It turns off the old 'com.spotify:docker-maven-plugin' and uses 'io.fabric8:docker-maven-plugin' instead. Few other improvements.

EMS: Broker-CEP: Added queuing and retrying, for event publishing to local broker and event forwarding to the next groupings. This applies to generated events captured by 'BrokerCepStatementSubscriber' instances. By default, failed publish/forward attempts will be repeated forever. A retry limit (num. of retries or max retry duration) can be set in 'eu.melodic.event.brokercep.properties' by setting either 'brokercep.max-event-forward-retries' or 'brokercep.max-event-forward-duration' (in millis).

EMS: Broker-CEP, config-files: Changed 'brokerUrl' field in 'BrokerCepProperties' class (i.e. 'brokercep.broker-url' property), into List of broker connector URLs (the 1st is the main connector). Removed 'brokerUrlProperties' and 'clientAuthRequired' properties and related code (they were appended to the main connnector URL). Removed unneeded fields 'defaultIpAddress' and 'publicIpAddress'. Extended 'BrokerConfig' class to initialize all connectors in 'brokerUrl' (not only the main and 2 additional as before). Connectors can arbitrarily be either SSL or non-SSL. Updated configuration files (eu.melodic.event.brokercep.properties).

EMS: Broker-CEP, Util: Removed code related to replacing occurrences of '%{DEFAULT_IP/PUBLIC_IP}%' to their actual values. Removed unused methods from 'IKeystoreAndCertificateProperties' and 'KeystoreAndCertificateProperties'. Few minor code improvements.

EMS: Baguette Client Install: Removed occurrences of '%{DEFAULT_IP/PUBLIC_IP}%' from AbstractInstallationHelper class

EMS: Control Service, config-files: Changed 'ControlServiceProperties.IpSetting' enum values to DEFAULT_IP and PUBLIC_IP (from '%{DEFAULT_IP}%' and '%{PUBLIC_IP}%'), and updated occurrences in config. files. Added EMS_SERVER_ADDRESS and EMS_CLIENT_ADDRESS variables in config. files and replaced ${IP_SETTING} occurrences with them. From now on IP_SETTING will only store the IP discovery setting (and will not be used as an IP address setting).

EMS: Control Service: Added 'getServerIpAddress()' method in ControlServiceCoordinator and replaced uses of 'coordinator.getControlServiceProperties().getIpSetting()' for determining the EMS server's IP address

EMS: Util, Control Service, Baguette Client, config-files: Added 'NetUtilPostProcessor' class for registering 'NetUtilPostProcessor.NetUtilPropertySource' responsible for providing values to ${DEFAULT_IP} and ${PUBLIC_IP} config. placeholders. Added 'NetUtilPostProcessor' in 'spring.factories' files of EMS server and Baguette Client for automated inclusion by Spring Boot. Changed occurrences of %{DEFAULT_IP}% and %{PUBLIC_IP}% with ${DEFAULT_IP} and ${PUBLIC_IP} respectively (usages via ${IP_SETTING} were not considered).

EMS: Control Service: Removed '@NonNullApi' annotations that cause compile time error, and also removed the 'com.google.code.findbugs-jsr305' workaround dependency. Marked dependencies in pom.xml that cause 'BeanPostProcessorChecker' to issue warnings. Commented out 'spring-boot-admin-starter-client' dependency
