Code Issues Proposed changes

Update git submodules 

* Update monasca-persister from branch 'master'
  - Merge "Update all columns in metrics on an update to refresh TTL"
  - Update all columns in metrics on an update to refresh TTL
    
    Cassandra Time to Live (TTL) is applied per-column in a
    row, and with a default TTL for the table.  The Cassandra
    driver appears to have been written with a misunderstanding
    that the TTL was per-row, and as a result the update
    statements were written to avoid writing all cells.
    But that results in some cells in the row not being updated,
    and after their TTL expires they are removed, so a metric
    query may result in partial data (updated_at set but
    metric_id and created_at missing).
    
    This fix changes the statement used when a new measurement
    is received to use the same insert statement for the metric
    row and thus refresh the TTL for all the columns.
    
    A follow on patch should be created to remove the Update
    statements for Measurements, and consider refactoring/removing
    the caching model.
