surface keys as argument/option to control log content

[nicholas-masel]

          In general, it might be a good idea to make it so the users can turn off/on different elements of logging, rather than always doing them. 

logrx/R/log.R

Line 110 in 678a34c

set_log_element("lint_results", get_lint_results(file))

Based on the code in the function log_config(), you could update to have an argument where the user can set which elements they would like to capture for the log. With "keys" being hardcoded within the function, it really isn't config-ing in the user sense.
