Endpoints for ticket information

[h1alexbel]

We should implement a few endpoints for getting ticket information, in the database we need to store issue number, repo and full file path to the related job, and status; for instance:

issue number: #34
repo: tracehubpm/pmo
job: .trace/jobs/fix-blah-blah-blah.yml
status: status of the ticket, opened or closed.

Probably, we need 2 read-endpoints that will return us issue number by full path + repo and full path by issue number + repo.

And we need 1 write-endpoint for submitting ticket.

blocks: tracehubpm/tracehub#31, tracehubpm/tracehub#32, tracehubpm/tracehub#33

We should conduct those tickets to implement it right
