    [FLINK-19192] Set connection pool size to 1024
    
    This commits increase the max size of the http connection pool to
    1024. The connection pool holds connections to the various endpoints
    and possibly various endpoint instances. The remote server can decide
    that they will not keep the connection alive. An idle connection
    would be evicted after 1 minute of inactivity.
    
    This closes #146.
