[sidr] docco changes from minutes

[Randy Bush <[e-mail]>]

so i reviewed the minutes from last month, looking for what i had to hack
in the docs i edit.  i found very little.  essentially

    <t>A prudent operator will pre-provision each router's 'next' key in
      the RPKI so that, in case of compromise of the current key, there
      is no propagation delay for provisioning the new key.</t>

and

    <t>The operator should be aware that BGPsec, as any other policy
      change, can cause traffic shifts in their network.  And, as with
      normal policy shift practice, a prudent operator has tools and
      methods to predict, measure, modify, etc.</t>

surely there was more.  help!!!
