Now that we added merge commit template function,
we don't need this checkbox. It wouldn't work with template.
This commit also deprecates defaultMergeCommitMessageWithDescription
in graphql. This field ignores mergeCommitTemplate, and doesn't
serve any function internally anymore.
Users are encouraged to use new merge commit template feature instead.

Changelog: deprecated

This change allows editing project's merge_commit_template
in project settings. Additionally it adds documentation
on merge commit template feature.

Use new merge_commit_template field (when set) to create default value
for merge commit message.

Changelog: added

This commit adds merge_commit_template column in project_settings.
It also adds this field to project's model.
