ensure_resource: fix documentation typo
(#21416) Allow file_line to match multiple lines

Without this commit the file_line type will outright fail if multiple
lines match the given regex. This commit allows the file_line type and
provider to optionally match and modify all matching lines.

added delete_values() and delete_undef_values() functions
Merge pull request #166 from ptomulik/delete_undef_values

Add delete_values() and delete_undef_values() functions
changed the validate_slength function to accept a min length

An optional third parameter can be given a min length. The function
then only passes successfully, if all strings are in the range
min_length <= string <= max_length

update and fix function and unit tests

the check for the minlength has to be written differently
because 0 values should be possible. We now check
a) if the input is convertible, and throw a ParseError and
b) if the input .is_a?(Numeric) and ask for a positive number
it's not as clean as for maxlength, but keeps a similar behaviour

refined the error checking for the min length

try to convert to Integer(args[2]) and fail,
if it's not possible

changed the tests accordingly to the new parameter checking
Merge pull request #167 from mhellmic/minlength

extend the validate_slength function to accept a minimum length
