Daniel Nephin c9bc5f92b7 envoy: fix bootstrap deadlock caused by a full named pipe
Normally the named pipe would buffer up to 64k, but in some cases when a
soft limit is reached, they will start only buffering up to 4k.
In either case, we should not deadlock.

This commit changes the pipe-bootstrap command to first buffer all of
stdin into the process, before trying to write it to the named pipe.
This allows the process memory to act as the buffer, instead of the
named pipe.

Also changed the order of operations in `makeBootstrapPipe`. The new
test added in this PR showed that simply buffering in the process memory
was not enough to fix the issue. We also need to ensure that the
`pipe-bootstrap` process is started before we try to write to its
stdin. Otherwise the write will still block.

Also set stdout/stderr on the subprocess, so that any errors are visible
to the user.

Fix envoy 1.10 exec (#5964)
* Make exec test assert Envoy version - it was not rebuilding before and so often ran against wrong version. This makes 1.10 fail consistenty.

* Switch Envoy exec to use a named pipe rather than FD magic since Envoy 1.10 doesn't support that.

* Refactor to use an internal shim command for piping the bootstrap through.

* Fmt. So sad that vscode golang fails so often these days.

* go mod tidy

* revert go mod tidy changes

* Revert "ignore consul-exec tests until fixed (#5986)"

This reverts commit 683262a686.

* Review cleanups
