Adding default value to verify hostname

[bibith4]

Description

This issue was identified as part of addressing a SonarQube warning in a static scan. The warning, 'Enable server hostname verification on this SSL/TLS connection,' was found in PrometheusClient.java. Upon investigation, we determined it to be a false positive.
This change adds a default value to the configuration property verify-host-name, which can be passed from the Preso UI. Based on this configuration value, a hostnameVerifier object is created. If the configuration property is set to false, the hostname verifier is adjusted to accept all hostnames; otherwise, it will perform hostname verification. To enable hostname verification by default, we are setting the verifyHostName variable to true in the PrometheusConnectorConfig.java file
