The following configration properties are optional for the ACME plugin to use. They allow reusing an existing ACME

LetsEncrypt: Using a pre-existing ACME account
-----------------------------------------------
Let's Encrypt allows reusing an existing ACME account, to create and especially revoke certificates. The current
implementation in the acme plugin, only allows for a single account for all ACME authorities, which might be an issue,
when you try to use Let's Encrypt together with another certificate authority that uses the ACME protocol.
To use an existing account, you need to configure the `ACME_PRIVATE_KEY` and `ACME_REGR` variables in the lemur
configuration.
`ACME_PRIVATE_KEY` needs to be in the JWK format::
{
"kty": "RSA",
"n": "yr1qBwHizA7ME_iV32bY10ILp.....",
"e": "AQAB",
"d": "llBlYhil3I.....",
"p": "-5LW2Lewogo.........",
"q": "zk6dHqHfHksd.........",
"dp": "qfe9fFIu3mu.......",
"dq": "cXFO-loeOyU.......",
"qi": "AfK1sh0_8sLTb..........."
}
Using `python-jwt` converting an existing private key in PEM format is quite easy::
import python_jwt as jwt, jwcrypto.jwk as jwk
priv_key = jwk.JWK.from_pem(b"""-----BEGIN RSA PRIVATE KEY-----
...
-----END RSA PRIVATE KEY-----""")
print(priv_key.export())
`ACME_REGR` needs to be a valid JSON with a `body` and a `uri` attribute, similar to this::
{"body": {}, "uri": "https://acme-staging-v02.api.letsencrypt.org/acme/acct/<ACCOUNT_NUMBER>"}
The URI can be retrieved from the ACME create account endpoint when creating a new account, using the existing key.
