API Feature Request: configure gitsync and sharing on spaces

[liliakai]

For my use case (a monorepo with many parallel spaces and highly granular team-based permissions), it would be really handy to configure the following properties of a particular Space via API calls:

1. The gitsync configuration including repository, monorepo directory, and custom commit message template.
2. The share settings, particularly granting read/write access to a specific Team in my Organization.
