feat: Sync API

[Monirzadeh]

This PR is trying to add sync functionality to shiori.
This API get last sync and list of id in client side as return deleted item and modified item from last sync.

This PR did sync without need to store deleted time, so close #903.

TODO:

• get modified item
• get deleted item list
• add pagination to the response
• show deleted item just in first page to avoid unneeded query on database
• done for postgress
• done for mariadb
• unittest
  • authentication test
  • 0 or negative id
  • return correct bookmark for specific timestamp
  • empty id if deleted not set
  • return correct id that not exist on database
  • deleted ID return correct id from databases
    this todolist can be update overtime

We have bellow problems in CI:

• 33f91a2 pass without mariadb database? is it possible api unittest not run on mariadb?
• 92307dc pass on windows macos and openbsd? those should field too because mariadb should field anyway. dose we run database mariadb test on all os or those tests just on linux for mariadb?
• postgress and mariadb tests run in CI just under Linux OS

Finally sync API :)
I am trying to do that without keeping deleted ids in database (we can change that if we see performance issue in long term)
Do we need any specific option in sync api like user can customize sort of modified bookmarks? or any other option?
Do we need more unit test (see We have bellow problems in CI section in first post of issue)?

I am not sure that using timestamp is the best option, but I am trying to choose safest option right now until we find better solution to handle time in database.

Thanks @DesarrolloAntonio it seems this PR has a bug that return empty imgURL for bookmarks.
it because of the way shiori detect state of files in server. i should find the best solution to fix this that i prefer that shiori save status of file(archive, ebook,image,etc) on database too
we need refactor some logic of shiori.
@fmartingr what do you think? any other solution do you prefer?
