Upgrade hashicorp/consul-template dependency

[tomhjp]

• Includes sprig template functions
• Includes improvements to writeTo template function
• Adds new test case for sprig functions and slightly improves the error reporting when the test fails

[calvn]

Thanks for adding the test against sprig!

Looks like the tests are failing because TemplateConfig.Command is no longer a string?

vault/command/agent/config/config_test.go

Line 678 in 99e2132

Command: pointerutil.StringPtr("restart service foo"),

And apparently Command is deprecated in favor of Exec now.

Looks like we should check for Exec in those tests, something like:

Edit, nevermind, something like this seems to work:

Command:        []string{"restart service foo"}
