On systems that /bin/sh is served by shells other than bash, or
shells that don't implement the same syntax as the bash printf builtin,
printf -- fails to produce the output necessary for standalone operation.
The test case for this was SmartOS, which uses ksh93 as its /bin/sh.
This change uses the more generic method of passing a format parameter
of a single string, and then the argument to replace it with.
When using vault_cli with a kv2 path, it isn't working. I have the following error:
```
WARNING! The following warnings were returned from Vault:
* Invalid path for a versioned K/V secrets engine. See the API docs for the
appropriate API endpoints to use. If using the Vault CLI, use 'vault kv put'
for this operation.
```
The new way to write data is to use `vault kv put`, it is compatible with kv1 and kv2.
Ref: https://www.vaultproject.io/docs/commands#reading-and-writing-data
```
The original version of K/V used the common read and write operations. A more advanced K/V Version 2 engine was released in Vault 0.10 and introduced the kv get and kv put commands.

Updated dns_servercow.sh to support txt records with multiple entries. This supports wildcard certificates that require txt records with the same name and different contents.
Updated dns_servercow.sh to support txt records with multiple entries. This supports wildcard certificates that require txt records with the same name and different contents.
The API now supports a POST route for adding records. Therefore
checking for already existing records and including them in a PATCH
request is no longer necessary.
Add and use _readaccountconf_mutable_default and
_saveaccountconf_mutable_default helpers to capture
common default value handling.
New approach also eliminates need for separate
underscore-prefixed version of each conf var.
