Package name change for callingserver to callautomation (Azure#30736)

Changing name of callingserver to callautomation. This change will be done by the following steps:
1. Duplicate the code with new package name(sdk/communication/azure-communication-callautomation)  [Done in this step]
2. Based on the new code, a new pipeline will be automatically created. Verify the pipeline and do sanity test on the generated artifact. Make sure everything works perfectly under the new package name.  [Will be done by merging this PR]
3. Merge a PR to remove sdk/communication/azure-communication-callingserver
4. Submit request to Engineering System channel in Teams for removing the old pipeline(callingserver pipeline)

+# Azure Communication CallingServer Service client library for Java
+
+This package contains a Java SDK for Azure Communication CallingServer Service. Server Test
+
+[Source code][source] | [Package (Maven)][package] | [API reference documentation][api_documentation]
+| [Product documentation][product_docs]
+
+## Getting started
+
+### Prerequisites
+
+- An Azure account with an active subscription. [Create an account for free](https://azure.microsoft.com/free/?WT.mc_id=A261C142F).
+- [Java Development Kit (JDK)](https://docs.microsoft.com/java/azure/jdk/?view=azure-java-stable) version 8 or above.
+- [Apache Maven](https://maven.apache.org/download.cgi).
+- A deployed Communication Services resource. You can use the [Azure Portal](https://docs.microsoft.com/azure/communication-services/quickstarts/create-communication-resource?tabs=windows&pivots=platform-azp) or the [Azure PowerShell](https://docs.microsoft.com/powershell/module/az.communication/new-azcommunicationservice) to set it up.
+
+### Include the package
+
+[//]: # ({x-version-update-start;com.azure:azure-communication-callautomation;current})
+```xml
+<dependency>
+    <groupId>com.azure</groupId>
+    <artifactId>azure-communication-callautomation</artifactId>
+    <version>1.0.0-beta.5</version>
+</dependency>
+```
+[//]: # ({x-version-update-end})
+
+## Key concepts
+This is the restart of CallingServer Service. It is renamed to Call Automation service and being more intuitive to use.
+
+`CallAutomationClient` provides the functionality to make call, answer/reject incoming call and redirect a call.
+
+`CallConnection` provides the functionality to perform actions in an established call connection such as adding participants and terminate the call.
+
+`CallMedia` introduces media related functionalities into the call.
+
+`CallRecording` provides the functionality of recording the call.
+
+`EventHandler` provides the functionality to handle events from the ACS resource.
+
+## Examples
+
+To be determined.
+
+## Troubleshooting
+
+If you recieve a CommunicationErrorException with the messagae: "Action is invalid when call is not in Established state." This usually means the call has ended. This can occur if the participants all leave
+the call, or participants did not accept the call before the call timed out. 
+
+If you fail to start a call because of an HMAC validation error, be sure your access key is correct, and
+that you are passing in a valid conversation id.
