Bitbucket Integration

[amaelftah]

reference
#36 #50 #176 #229

Notes :-

• bibucket returns uuids so i had to add the migrations to change tables that contains provider and provider_id columns

• without bitbucket token sent as a request header , it won't retrieve the current user private repos that he owns so i had to change the request helper method

• i added the refresh_token column , cause bitbucket token expires after 1 hour as mentioned in the documentation , also i provided a screenshot of how the object will look like
  refreshToken

• in handleProviderCallback the user from socialite must be updated , to update his refresh_token and token

• some of the methods uses version 1.0 of the api , because these end points aren't supported in version 2.0

• in the readCollaborators if the repo owner is logged in and currently importing the repo into GitScrum the method will get all associated collaborators , otherwise , it won't get associated collaborators, and the reason for this as mentioned in the documentation priviliges , Only the repository owner, a team account administrator, or an account with administrative rights on the repository can make this call
