* (#2044) (#1957) Update git.rake - configurable max concurrent connections
Default git_max_concurrent_connections is set to 10 hosts per group.
Default git_wait_interval is set to 3 seconds.
This enables deployments for large number of servers with default Gitlab or similar git server configuration with default SSH settings (max 10 concurrent connections).
* ADD: rspec tests for default values
* UPDATE: docs/documentation/getting-started/configuration/index.markdown
Capistrano gems shouldn't be loaded within a Rails (or any) app. They
are intended to be used by the cap command, not within Rails itself. At
best, `require: true` (the default) is unnecessary; at worst, it can
cause conflicts as encountered here:

Update our docs to recommend `require: false` just to be safe.
