partitioned tables in config

[mkabilov]

in case of setting up replication for child tables of the partitioned table it will be useful to specify pattern for tables, i.e. instead of :

    partitions.report_2017_03_01:
        main_table: report
        engine: CollapsingMergeTree
        init_sync_skip_truncate: true
    partitions.report_2017_04_01:
        main_table: report
        engine: CollapsingMergeTree
        init_sync_skip_truncate: true
    partitions.report_2017_05_01:
        main_table: report
        engine: CollapsingMergeTree
        init_sync_skip_truncate: true
    partitions.report_2017_01_01:
        main_table: report
        engine: CollapsingMergeTree
        init_sync_skip_truncate: true

write something like that:

    partitions.report_*:
        main_table: report
        engine: CollapsingMergeTree
        init_sync_skip_truncate: true
