Bundle git inside gis

[nqminhuit]

To use gis user must install git under /usr/bin/git some people may install in different directory which make it harder to config. Explore if we can bundle git into the native image.

Final decision: we will bundle jgit as dependency

• jgit status #100
• jgit fetch #101
• jgit checkout #102
• jgit pull #103
• jgit rebase #104
• jgit branch -d #105
• jgit remote prune #106
• jgit prune local merged branch #107
• jgit stash and pop #108
