[GOCA] template escaping problem

[treywelsh]

Description

Since issue #5785 and related PR #5782 merged the terraform provider doesn't handle anymore multiline strings (I made an update on the goca dependencies to point to one 6.4).
Before this PR, goca only escaped double quotes.

See the related provider issue.
At first this change seems positive to me: before #5782 we had some complex escaping issues like in this provider issue, however it seems that we don't want to escape all characters.

Escaping is done in String() method on dynamic template.

To Reproduce
It should be easy to reproduce with a goca example:

package main

import (
	"fmt"
	"github.com/OpenNebula/one/src/oca/go/src/goca/schemas/vm"
)

func main() {
	tpl := vm.NewTemplate()
	tpl.Add("KEY", `line1
	line2`)

	fmt.Println(tpl.String())
}

Will print with goca 6.4:

KEY="line1\n\tline2"

Expected behavior

Not sure on how should we handle this. Should we rewrite a more specific quote method to not handle '\n' ?
