1. Proposed title of this feature request:
   Support for Bitbucket Server OAuth 2.0
2. What is the nature and description of the request?
   Client is trying to connect to DevSpaces with their internal Bitbucket Server using OAuth 2.0. Unfortunately, this does not work. So they are quite concerned to get this working in their env.

Although the docs only mention that OAuth 2.0 works for Bitbucket Cloud, client is using  Bitbucket Server and does not have OAuth 1.0. So they are kind of cornered here.  

1. Why does the customer need this? (List the business requirements here)
   Client needs Bitbucket Server OAuth 2.0 to be included in the as they are using this for the version control in their environment.{}
2. Addition details:
   As per official DevSpaces documentation currently OAuth 2.0 works for Bitbucket Cloud and OAuth 1.0 for a Bitbucket Server. Client needs OAuth 2.0 to be included for the Bitbucket Server.
