Trim white spaces & newlines from env vars

[Kyle-Law]

Added .strip.gsub(/\s+/, " ") method to environment variables:
var_hash['value'].strip.gsub(/\s+/, " ")

Example:

Input:

p " space-between with space ".strip.gsub(/\s+/, " ")
p " first line \n 2nd line".strip.gsub(/\s+/, " ")
p " two newlines \n\n".strip.gsub(/\s+/, " ")

Output:

"space-between with space"
"first line 2nd line"
"two newlines"

Alternative:

• there's a .squish method in rails, but not available in pure ruby script
• .split.join(' ') does the trick as well

Hey @jsastrillo. Please QA this recipe by adding env vars to a v6 environment which have whitespace at the start and end, and new lines, then checking that those are stripped from the env.cloud when this version of the recipe is used.

This does not solve it. Tested with overlay but white space still exists in /env.cloud

export TEST="test test   "
