log: add a config to simplify graphs Summary: This could help simplify the graph a lot for repos with lots of merges. For example, logging tags on linux.git looks like: o fb893de3 Yesterday at 17:28 master ├─┬─┬─┬─┬─┬─┬─┬─┬─┬─╮ ╷ ╷ ╷ ╷ ╷ ╷ ╷ ╷ ╷ ╷ o bcf87687 Aug 02 at 14:21 v5.8 ╷ ╷ ╷ ╭─────┬─┬───┬─╯ ╷ ╷ ╷ ╷ ╷ ╷ ╷ ╷ ╷ o 92ed3019 Jul 26 at 14:14 v5.8-rc7 ╷ ╷ ╷ ╭─────┬─┬─┬─╯ ╷ ╷ ╷ ╷ ╷ ╷ ╷ ╷ o ba47d845 Jul 19 at 15:41 v5.8-rc6 ╷ ╷ ╷ ╭─┬─┬─┬─┬─╯ ╷ ╷ ╷ ╷ ╷ ╷ ╷ o 11ba4688 Jul 12 at 16:34 v5.8-rc5 ╷ ╷ ╷ ╭─┬─┬─┬─╯ ╷ ╷ ╷ ╷ ╷ ╷ o dcb7fd82 Jul 05 at 16:20 v5.8-rc4 ╷ ╷ ╷ ╭─┬─┬─┤ ╷ ╷ ╷ ╷ ╷ o ╷ 9ebcfadb Jun 28 at 15:00 v5.8-rc3 ╷ ╷ ╭─┬─┬─╯ ╷ ╷ ╷ ╷ ╷ o ╷ 48778464 Jun 21 at 15:45 v5.8-rc2 ╷ ╷ ╷ ╭─╯ ╷ ╷ ╷ ╷ o ╷ b3a9e3b9 Jun 14 at 12:45 v5.8-rc1 ╭─┬─┬─┼─┬─┬─┬─┬─┬─┬─┬─┬─┬─┬─┬─┬─╮ ╷ ╷ o ╷ ╷ ╷ ╷ ╷ ╷ ╷ ╷ ╷ ╷ ╷ ╷ ╷ ╷ 3d77e6a8 May 31 at 16:49 v5.7 ╭─┬─┴───────┬───────────┬─┬───┬─╮ ╷ o ╷ ╷ ╷ ╷ ╷ ╷ ╷ ╷ ╷ ╷ ╷ ╷ ╷ ╷ 9cb1fd0e May 24 at 15:32 v5.7-rc7 ╷ ╰─────────┬─────────────┬─┬─┬─╮ ╷ ╷ ╷ ╷ ╷ ╷ ╷ ╷ ╷ ╷ ╷ ╷ ╷ ╷ o b9bbe6ed May 17 at 16:48 v5.7-rc6 ╭───────────┬─────────────┬─┬─┬─╯ ╷ ╷ ╷ ╷ ╷ ╷ ╷ ╷ ╷ ╷ ╷ ╷ ╷ o 2ef96a5b May 10 at 15:16 v5.7-rc5 ╭───────────┬─────────────┬─┬─╯ ╷ ╷ ╷ ╷ o ╷ ╷ ╷ ╷ ╷ ╷ ╷ ╷ 0e698dfa May 03 at 14:56 v5.7-rc4 ╭───────────┴───────────┬─┬─╮ o ╷ ╷ ╷ ╷ ╷ ╷ ╷ ╷ ╷ ╷ ╷ 6a8b55ed Apr 26 at 13:51 v5.7-rc3 ╰─────────────────┬───────┬─╮ ╷ ╷ ╷ ╷ ╷ ╷ ╷ ╷ ╷ ╷ o ae83d0b4 Apr 19 at 14:35 v5.7-rc2 ╷ ╷ ╷ ╷ ╷ ╷ ╷ ╷ ╷ ╭─┤ ╷ ╷ ╷ ╷ ╷ ╷ ╷ ╷ ╷ o ╷ 8f3d9f35 Apr 12 at 12:35 v5.7-rc1 ╭─┬─┬───────┬─────┬─┬─┬─┬─┼─╮ ╷ ╷ ╷ ╷ ╷ ╷ ╷ ╷ ╷ ╷ ╷ ╷ o ╷ ╷ 7111951b Mar 29 at 15:25 v5.6 ╷ ╭─────────┬─────┬─┬─┬─┴───╮ ╷ ╷ ╷ ╷ ╷ ╷ o ╷ ╷ ╷ ╷ ╷ ╷ ╷ 16fbf79b Mar 22 at 18:31 v5.6-rc7 ╷ ╷ ╭───────┴─────┬─┬─┬─────╮ ╷ ╷ ╷ ╷ ╷ ╷ ╷ ╷ ╷ ╷ ╷ ╷ o fb33c651 Mar 15 at 15:01 v5.6-rc6 ╷ ╭─┬─────────────┬─┬─┬─────╯ ╷ ╷ ╷ ╷ ╷ ╷ ╷ ╷ ╷ ╷ o ╷ 2c523b34 Mar 08 at 17:44 v5.6-rc5 ╷ ╭─┬─────────────┬─┬─╯ ╷ ╷ ╷ o ╷ ╷ ╷ ╷ ╷ ╷ ╷ ╷ 98d54f81 Mar 01 at 14:38 v5.6-rc4 ╷ ╭─┴─────────────┬─╮ ╷ ╷ ╷ ╷ ╷ ╷ ╷ ╷ ╷ o ╷ f8788d86 Feb 23 at 16:17 v5.6-rc3 ....

Under the hood, the difference is how `reachableroots` gets calculated. See also D22657197 (https://github.com/facebookexperimental/eden/commit/a5c36fd0b1e3590e04fc274ff7fc02898fcee798) and D22368827 (https://github.com/facebookexperimental/eden/commit/da42f2c17ee27725e9523affcc56877c4b74813b).
