Tor support for blockchain watchdogs (#1907)

We now query blockchain watchdogs over Tor when it's activated.
Some watchdogs are automatically disabled because they have no
support for Tor.

We also let users change the list of watchdogs that should be run
from their `eclair.conf`.

features from using Tor, use both.
Note, that bitcoind should be configured to use Tor as well (https://en.bitcoin.it/wiki/Setting_up_a_Tor_hidden_service).
### Blockchain watchdogs
Eclair version 0.5.0 introduced blockchain watchdogs, that fetch bitcoin headers from various sources in
order to detect whether the node is being eclipsed. Eclair supports four sources at the moment:
* blockchainheaders.net
* blockcypher.com
* blockstream.info
* mempool.space
Once `eclair.socks5.enabled` is set to `true` blockchain watchdogs connect to their respective sources over Tor.
The most Tor-friendly sources are `blockstream.info` and `mempool.space` since they have native onion endpoints for their APIs.
Tor support for `blockchainheaders.net` is not implemented (yet), so it gets automatically disabled when `eclair.socks5.enabled = true` to protect user's privacy.
`blockcypher.com` can be flaky when used over Tor. It imposes rate limits and sometimes (rather often in fact) requires solving CAPTCHA.
If you experience similar troubles with `blockcypher.com` use this config parameter to disable it:
```
eclair.blockchain-watchdog.sources = [
"bitcoinheaders.net",
"blockstream.info",
"mempool.space"
]
```
