DRAFT: Implement WRITE_LEASE_VALIDITY

[spetrosi]

This functionality still doesn't work. Keeping the PR for history.

Fails with the following:

TASK [linux-system-roles.mssql : Print the output of the sqlcmd command for configure_listener.j2 if not empty] ******************************************************************************
ok: [primary] => {
    "__mssql_sqlcmd_input_file.stdout_lines": [
        "Adding the ExampleAG-listener listener to the ExampleAG availability group",
        "Msg 19407, Level 16, State 2, Server primary, Line 8",
        "The lease between availability group 'ExampleAG' and the Windows Server Failover Cluster has expired. A connectivity issue occurred between the instance of SQL Server and the Windows Server Failover Cluster. To determine whether the availability group is failing over correctly, check the corresponding availability group resource in the Windows Server Failover Cluster.",
        "Added the ExampleAG-listener listener successfully"
    ]
}
