Better templates

[pshirshov]

Templating support is dirty and not flexible enough

• [ ] We need to support thread id and thread name separatedly
• [ ] We need to come up with a better formatter patterns
• [ ] We should allow user to support more formatting rules
• [ ] Static configs are inconvenient to work with. I think we should "register" logger components and use shorthand names (or introduce aliases, in worst case - play with hocon expansions)

Formatting rules:

• [x] Maximum width and ellipsing on/off
• [x] Minimization on/off, how many elements to leave at the right side
• [ ] Suggested width + left/right alignment (with and without trimming/ellipsing)
• [ ] Optionally use unicode dots symbol instead of ... for ellipsing
• [ ] Platform-independent coloring (${red}something${clear})

Maybe we shouldn't bother with cryptic format and use smth like ${id}[ellipsis=on, limit=10, align=left], etc
