1ab49b81cf32b6ef9e312a0a8ac45c68a3262f0d Add in/out connections to rpc getnetworkinfo (Jon Atack)
Pull request description:
This is basic info that is present in the GUI that I've been wishing to have exposed via the RPC and CLI without needing a bash workaround or script. For human users it would also be useful to have it in `-getinfo`.
`bitcoin-cli getnetworkinfo`
```
"connections": 15,
"connections_in": 6,
"connections_out": 9,
```
`bitcoin-cli -getinfo`
```
"connections": {
"in": 6,
"out": 9,
"total": 15
},
```
Update the tests, RPC help, and release notes for the changes. Also fixup the `getnettotals` timemillis help while touching `rpc/net.cpp`.

Reviewers can manually test this PR by [building from source](https://jonatack.github.io/articles/how-to-compile-bitcoin-core-and-run-the-tests), launching bitcoind, and then running `bitcoin-cli -getinfo`, `bitcoin-cli getnetworkinfo`, `bitcoin-cli help getnetworkinfo`, and `bitcoin-cli help getnettotals` (for the UNIX epoch time change).
