3VAbdAVE d8637b2c0f fixes #3359
Ubiquiti removed keytool (and java) from recent releases of Unifi OS. This moves from keytool to openssl's native pkcs12.

Tested on Unifi Dream Machine which runs Unifi OS and a built-in Unifi controller.

Also added backup of existing files prior to change in case anything goes wrong, and update system configuration with compatible ciphers.

# Here is a script to deploy cert on a Unifi Controller or Cloud Key device.
# It supports:
# - self-hosted Unifi Controller
# - Unifi Cloud Key (Gen1/2/2+)
# - Unifi Cloud Key running UnifiOS (v2.0.0+, Gen2/2+ only)
# - Unifi Dream Machine
# This has not been tested on other "all-in-one" devices such as
# UDM Pro or Unifi Express.
#
# OS Version v2.0.0+
# Network Application version 7.0.0+
# OS version ~3.1 removed java and keytool from the UnifiOS.
# Using PKCS12 format keystore appears to work fine.
#
# Please report bugs to https://github.com/acmesh-official/acme.sh/issues/3359
#returns 0 means success, otherwise error.
# The deploy-hook automatically detects standard Unifi installations
# for each of the supported environments. Most users should not need
# to set any of these variables, but if you are running a self-hosted
# Controller with custom locations, set these as necessary before running
# the deploy hook. (Defaults shown below.)
#
# Settings for Unifi Controller:
# Location of Java keystore or unifi.keystore.jks file:
#DEPLOY_UNIFI_KEYSTORE="/usr/lib/unifi/data/keystore"
# Keystore password (built into Unifi Controller, not a user-set password):
#DEPLOY_UNIFI_KEYPASS="aircontrolenterprise"
# Command to restart Unifi Controller:
#DEPLOY_UNIFI_RELOAD="service unifi restart"
#
# Settings for Unifi Cloud Key Gen1 (nginx admin pages):
# Directory where cloudkey.crt and cloudkey.key live:
#DEPLOY_UNIFI_CLOUDKEY_CERTDIR="/etc/ssl/private"
# Command to restart maintenance pages and Controller
# (same setting as above, default is updated when running on Cloud Key Gen1):
#DEPLOY_UNIFI_RELOAD="service nginx restart && service unifi restart"
#
# Settings for UnifiOS (Cloud Key Gen2):
# Directory where unifi-core.crt and unifi-core.key live:
#DEPLOY_UNIFI_CORE_CONFIG="/data/unifi-core/config/"
# Command to restart unifi-core:
#DEPLOY_UNIFI_RELOAD="systemctl restart unifi-core"
#
# At least one of DEPLOY_UNIFI_KEYSTORE, DEPLOY_UNIFI_CLOUDKEY_CERTDIR,
# or DEPLOY_UNIFI_CORE_CONFIG must exist to receive the deployed certs.
