[Feature][Plugin] Add Tempo (Jira Tempo Timesheets) plugin

[acarmisc]

Description

Add a new plugin for Tempo Timesheets (Jira Tempo) that ingests worklogs and teams into DevLake.

Scope

• Worklog Collection: Fetches worklogs from Tempo API v4 with pagination and date filtering
• Team Management: Collects Tempo teams for scope configuration
• Domain Mapping: Maps Tempo worklogs to DevLake's issue_worklogs domain layer
• UI Integration: Full configuration UI in config-ui (connection form, scope config)

Data Model

• _tool_tempo_worklogs — raw worklog data (tempo_worklog_id, issue_id, time_spent_seconds, billable_seconds, start_date, start_time, description, author_account_id)
• _tool_tempo_teams — Tempo team metadata
• _tool_tempo_connections — connection config (endpoint, token, proxy, rate_limit)
• Domain mapping to issue_worklogs (id format: tempo:TempoWorklog:{TempoWorklogId})

Dependencies

• Requires Jira plugin for issue ID mapping (jira:JiraIssues:{ConnectionId}:{IssueId})

Implementation

Standalone plugin already developed at acarmisc/apache-devlake-jira-tempo-plugin. Ready to contribute upstream.
