dict: add dict_set_dynstr_with_alloc

There is an overwhelming no. of instances of the following pattern in
glusterd module.

    ...

    char *dynstr = gf_strdup (str);
    if (!dynstr)
       goto err;
    ret = dict_set_dynstr (dict, key, dynstr);
    if (ret)
       goto err;

    ...

With this changes it would look as below,

   ret = dict_set_dynstr_with_alloc (dict, key, str);
   if (ret)
       goto err;
