This fixes#9292 by adding a section to the language server settings
that allows users to specify the binary path and arguments with which to
start up a language server.
Example user settings for `rust-analyzer`:
```json
{
"lsp": {
"rust-analyzer": {
"binary": {
"path": "/Users/thorstenball/tmp/rust-analyzer-aarch64-apple-darwin",
"arguments": ["--no-log-buffering"]
}
}
}
}
```
Constraints:
* Right now this only allows ABSOLUTE paths.
* This is only used by `rust-analyzer` integration right now, but the
setting can be used for other language servers. We just need to update
the adapters to also respect that setting.
Release Notes:
- Added ability to specify `rust-analyzer` binary `path` (must be
absolute) and `arguments` in user settings. Example: `{"lsp":
{"rust-analyzer": {"binary": {"path": "/my/abs/path/rust-analyzer",
"arguments": ["--no-log-buffering"] }}}}`
