Make scheduling policy used in schedule_recurrent configurable
Add support for a configuration option "scheduling_policy" in the config
file loaded by the 'swh scheduler schedule-recurrent' command. This
config entry allows to specify the scheduling policies used by the
schedule-recurrent tool, instead of having them hardcoded in the source
A visit type policy config entry should have at least a 'weight' value
for each policy.
Default values are unchanged.
scheduling_policy: git: - policy: already_visited_order_by_lag weight: 55 tablesample: 0.5 - policy: never_visited_oldest_update_first weight: 45 tablesample: 0.5
Note: there may not be configuration entries for all visit types, but if
a visit type policy is configured, the config entry should be complete (in other words, the merging of the configuration with the default values is only done at first config level).
