NR-306872: IAST support for CI/CD

[IshikaDawda]

• Honour new config security.iast_test_identifier
• Add test identifier header in web socket headers, with header name NR-CSEC-IAST-TEST-IDENTIFIER
• Add process start time header in web socket headers, with header name NR-CSEC-PROCESS-START-TIME

Mandatory Fields: The following fields are required to ensure accurate state tracking:

• Process Start Time (procStartTime): The timestamp when the application or process started.
• Traffic Start Time (trafficStartedTime): The time at which the CSEC agent recorded the first event.
• Scan Start Time (scanStartTime): The timestamp when the first control command (fuzz request) is processed at the SA.

Optional Fields: The following fields provide additional context and can be used to gain a deeper understanding of the application's state:

• Control Command Request Time (controlCommandRequestedTime): The timestamp of the first control command for fuzz request. This will never change.
• CSEC Activation Time (csecActivationTime): The timestamp when the CSEC agent will activate or activated.
• IAST Activation Time (iastDataRequestTime): The timestamp when the IAST Scan will start or started requesting control commands. (This is the time when IAST will send it’s first Data Pull Request for the particular scan window)
• Scan Active (scanActive): A boolean indicating whether the agent is actively scanning (IAST pull request are active) (Note: This field has no relation with scan end time).
