Publish OpenAPI JSON schemas for Visual Studio Code IntelliSense

Signed-off-by: Chanwit Kaewkasi <chanwit@gmail.com>

This change publishes the auto-generated JSON schemas as a single URL,
so that it is consumable by a tool like VS Code.

The CRD generator creates 2 files, a tar.gz for Kubeval,
and another one is a JSON file. The JSON file is a combination of
all schemas, put under the "oneOf" operator.

bootstrap: add BitBucket Server (previously known as Stash) support

The new command set is:
  flux bootstrap bitbucket-server --owner=<project> --username=<user> --repository=<repository name> --hostname=<domain> --token-auth

There is a parity in the capabilities with the other providers.

Prompt for access tokens in 'bootstrap' command

bufio's reader.ReadString includes any CRLF characters and we don't
want these in the resulting token because this leads to errors in the
authentication like this:

```
✗ failed to get Git repository
"https://github.com/kingdon-ci/jenkins-infra": Get
"https://api.github.com/repos/kingdon-ci/jenkins-infra

": net/http:
invalid header field value "Bearer gho_NNNNNsecrettokenMMMMM\n" for
key Authorization
```

This change adds functionality to both, `bootstrap github` and
`bootstrap gitlab` to prompt the user for the personal access tokens
if those can't be derived from the shell environment. Echoing is
turned off for better privacy.

Instead of having to interactively type the token or manually paste it
from the clipboard, users can also pipe it to Flux which comes in
handy e.g. when executing Flux remotely over an SSH connection:

```
$ echo 'asdf' | flux bootstrap github
```

Otherwise, Flux will prompt the user:

```
$ flux bootstrap github
Please type your GitHub personal access token:
```
