models: replace workflow.run_number with generation and restart number

[giuseppe-steduto]

Change the workflow table to split the run_number into two integers: one referring to the generation of the workflows, and the other one referring to the restart number, thus removing the limit of 9 restarts.

Closes #186.

To test the PR, these quick scripts might be come in handy: 1) Run the specified number of workflows on REANA (default 15), to be run from a workflow directory (such as roofit).

#!/bin/bash

# Set the default number of runs to 15 if no argument is passed
NUM_RUNS=${1:-15}

# Run the setup environment command
eval $(reana-dev client-setup-environment)

# Run the workflow the specified number of times
for (( i=1; i<=NUM_RUNS; i++ ))
do
  echo "Starting run $i of $NUM_RUNS..."
  reana-client run -w root6-roofit
  echo "Run $i submitted."
done

2) Restart a specific generation of the roofit demo workflow (default 1) a certain number of times (default 15). ./restart.sh 50 3 will restart root6-roofit.3 50 times.

#!/bin/bash

# Set the default number of runs to 15 if no argument is passed
NUM_RUNS=${1:-15}
TO_RESTART=${2:-1}

# Run the setup environment command
eval $(reana-dev client-setup-environment)

# Run the workflow the specified number of times
for (( i=1; i<=NUM_RUNS; i++ ))
do
  echo "Starting restart $i of $NUM_RUNS..."
  reana-client restart -w root6-roofit.$TO_RESTART
  echo "Restart $i submitted."
done
