Clearing Messages

Feature Description
One-to-one messages and group messages can be cleared.
When messages in a conversation are cleared, all the messages in the conversation will be cleared both locally and from the cloud, but the conversation itself will not be deleted.
Note: 
Do not use this API if you do not want to clear messages from the cloud.
If the last message is deleted, the lastMessage in the conversation will become the last but one message.
Clearing one-to-one messages
Call clearC2CHistoryMessage (Details) to clear one-to-one messages.
Sample code:
TencentImSDKPlugin.v2TIMManager.getMessageManager().clearC2CHistoryMessage(userID: "userid");
Clearing group messages

Sample code:
 TencentImSDKPlugin.v2TIMManager.getMessageManager().clearGroupHistoryMessage(groupID: "");
