fix(issue-57): truncate the bp branch name

fix: https://github.com/kiegroup/git-backporting/issues/57

This pr will ensure that if the provided/generated backport branch name
exceede the maximum branch name length set for git, which is 250 chars,
it truncates that name to 250 chars exactly.

In order to include as much commits as possible the branch name will
contain by default the shortened version of all commits
