GoDaddy enhancements

- Support for domains longer than 3 segments (ex. 1.www.mydomain.com).
- No need for GODADDY_BASE.  Domain will be automatically determined from full RR name.
- Update to delete challenge records.

Fix CNAME issues and support acme-dns (fixes #722, #308, #646, #600, #585)

Fix DOMAIN_CHAIN_LOCATION to copy correct file

detect Solaris derivates and add /usr/gnu/bin to PATH

add scripts to use IONOS DNS API

When FULL_CHAIN_INCLUDE_ROOT is set, DOMAIN_CHAIN_LOCATION was sending just the intermediate and server cert. Copying $FULL_CHAIN instead of $CERT_FILE+$CA_CERT fixes this.

Add manual upgrade instructions for v2.43

Fix upgrade url issue

Add pre and post upgrade sanity checks
Fixes #718

Use `latest` tag instead of `master` in installation instructions

Fix -preferred-chain argument (#712)
Show help if no domain specified (#705)

Show help if no domain specified (#705)

Tests for pr706 and fix276

Add debug statement to investigate failures when running in github actions

Force new certificate if key alg changes (fixes #276)

delete key file when key alg has changed

dns_scripts for Azure CLI

Temporarily revert changes to upgrade using `make`

Reduce test noise

Remove credentials from test repository, support dns tests from forks, improve upgrades, fix cUrl version checks

getssl uses cURL's version to determine what command
options are valid.

The previous shortcuts will fail when curl V8.10 is
released.  (8.9 is greater than 8.10).  V8 is planned
for release, in part to avoid a minor version of 100,
which also would fail.

check_version() will compare full or partial version
strings by component, and is true if $1 is at least $2.

Upgrade test checks for "error" in output.

But release descriptions can have "fix error in ..."

Don't run this check.  Checking that a new version is detected suffices.
