Variable replacement

Variable replacement rules in module fields.

Variables in module input fields are replaced following the standard Jinja templating rules, here are some examples:

Comment on source value	Source value (exact value of x)	Body to be replaced	Final result	Comment on final result
null value	null	{{ x }}	null	null value
string	hello	{{ x }}	hello	string
json	{"y":"world"}	{{ x }}	{"y":"world"}	json
string	{"y":"world"}	{{ x }}	{"y":"world"}	string
number	123	{{ x }}	123	number
string	123	{{ x }}	123	string
empty string		{{ x }}		empty string
string	{{ text }}	{{ x }}	{{ text }}	string
null value	null	{{ x.y }}	null	null value
string	hello	{{ x.y }}	null	null value
json	{"y":"world"}	{{ x.y }}	world	string
empty string		{{ x.y }}	null	empty string
json	{"y":"world"}	{{ x.y }}	world	string
string	{"y":"world"}	{{ x.y }}	null	null value
number	123	{{ x.y }}	null	number
string	123	{{ x.y }}	null	string
json	{"y":123}	{{ x.y }}	123	number
json	{"y":"123"}	{{ x.y }}	123	string
string	{{ text }}	{{ x.y }}	{{ text }}	string

Not replacing sections enclosed in double curly brackets

Use cases require to have a text between curly brackets NOT replaced by the templating engine.

An example body not to be replaced is {{ customer text that should remain in curly brackets }} In this case, the text not to be replaced can be formatted as follows to maintain the curly brackets

 {{ {{ customer text that should remain in curly brackets }} }}

where the final result would be in the final body (after replacement) is

{{ customer text that should remain in curly brackets }}
