Summary table column spacing is not optimal

[ahakanbaba]

If the user has used resource options other than the --customerTag, the column spacing can be suboptimal.

For example see here

$ ./wavectl show alert --name Kubernetes
ID               NAME                                                                                     STATUS                              SEVERITY
1523082347619    Kubernetes - Node Network Utilization - HIGH (Prod)                                      CHECKING                            WARN
1523082347824    Kubernetes - Node Cpu Utilization - HIGH (Prod)                                          CHECKING                            WARN
1523082348005    Kubernetes - Node Memory Swap Utilization - HIGH (Prod)                                  SNOOZED                             WARN

There is so much space between the NAME column and STATUS columns. The reason is that the column spacing is calculated using the alerts without considering the effects of other locally executed filters. In this example the --name Kubernetes command line param.

Seeing the full set of alerts, (without the --name Kubernetes option) shows the reason of the separation

There is an alert that has a really long name and even though that is not in the final displayed list, it caused the columns to be too widely separated.

All alerts matching the --customerTag are received from the Wavefront server, and they are further narrowed down on the wavectl client . The show summary table column separation should use the final set of alerts.
