secrets-template with >1 templates that include range statement causes dest/template mismatch

[smurfralf]

Scenario: I configure secrets-destination and secrets-template with multiple comma delimited values. Because secrets.go splits the annotation strings with "," as the delimiter, a template that includes

{{ range \$k, \$v := .Data }}

will split on the internal comma resulting in error

Submitted pod must contain same numbers of templates and secrets destinations
