Refactor connection factory (#181) 
* Start moving out URI from ConnectionContext

Create connections with an initial context. Database will set itself as context after connection has been created

* Migrate to simpler/decoupled factory in driver

This allows more freedom on how the connection is created. It will no longer need to have an explicit reference to the connection URI

* Introduce DB::Connection::Options

Move prepared_statements out from ConnectionContext

* Delegate options parsing to driver

DRY parsing connection options for database

* Introduce DB::Pool::Options

* Rename Driver#connection_pool_options to pool_options

* Drop driver getter from database

* Drop uri getter from database

* Add public Database#initialize method

* Drop :nodoc: Database#initialize

* Pass spec helper explicitly (to access methods within each spec)

* Update docs

* Update src/db/pool.cr

Co-authored-by: Beta Ziliani <beta@manas.tech>

* Use ConnectionBuilder instead of procs

* Fix inferred type when there is a single concrete connection type

* Update src/db/driver.cr
