[PATCH 0/5] Separate '--skip-refresh' from '--quiet' in 'reset', use '--quiet' internally in 'stash'

In the process of working on tests for 'git stash' sparse index integration, I found that the '--quiet' option in 'git stash' does not suppress all non-error output when used with '--index'. Specifically, this comes from an invocation of 'git reset' without the '--quiet' flag in 'reset_head()'. Upon enabling that flag, though, I discovered that 1) 'reset' does not refresh the index if '--quiet' is specified (as of [1]) and 2) 'git stash' needs the index to be refreshed after the reset.

This series aims to decouple the "suppress logging" and "skip index refresh" behaviors in 'git reset --mixed', then allow 'stash' to internally use reset with logs suppressed but index refresh enabled. This is accomplished by introducing the '--[no-]refresh' option and 'reset.refresh' config setting to 'git reset'. Additionally, in the spirit of backward-compatibility, '--quiet' and/or 'reset.quiet=true' without any specified "refresh" option/config will continue to skip 'refresh_index(...)'.

There are also some minor updates to the advice that suggests skipping the index refresh:

 * replace recommendation to use "--quiet" with "--no-refresh"
 * use 'advise()' rather than 'printf()'
 * rename the advice config setting from 'advice.resetQuiet' to to
   'advice.resetNoRefresh'
 * suppress advice if '--quiet' is specified in 'reset'

Finally, tests are added to 't7102-reset.sh' verifying whether index refresh happens when expected and to 't3903-stash.sh' verifying that 'apply --quiet' no longer prints extraneous logs.
