chore(integrations): query active integrations for vsts, stacktrace linking, syncing, webhooks

[cathteng]

Query for active integrations when:

• Doing an autofix setup check (non-active GH integrations will not make successful downstream calls)
• Editing a repository to be attached to a different integration
• Fetching installation metadata to process GH Enterprise webhook
• Fetching MSTeams integrations from various sources, used in MSTeams middleware
• Processing MSTeams webhooks
• Updating organization config for Opsgenie
• Validating Slack integration for incoming requests
• Syncing issues inbound and outbound
• Processing stacktrace links (we make an external API call to check if the file exists)
• Processing VSTS webhooks, client (for refresh token), and searching issues (calls client.search_issues)
