* treat private-key conn props as base64 encoded

- fix typo

* handle connecting with local keypair

* adds test for snowflake keypair auth

* remove unused arg

* remove id, and only call byte-array->string once

* dont reflect for conversion from byte-array to str

* remove inline def

* more cleanup

- mess with tests to find the fabled metabase ci snowflake user

* remove un-needed test

* handle conn uri in connection-details->spec

* make sure tests are actually running

* encode properties in the connection uri

* typehint private keyfile

* respond to some review comments

- add a test for can-connect? => true, even when jdbc/query returns falsey

* remove unused logging require

* adds assoc-qp

- which will be used to non-destructively "assoc" onto the snowflake
connection query params

* hook in u.qp/assoc-qp to better update conn uri

* kill a newline

* reuse `conn-str-with-additional-opts` on snowflake conn uri

* update use utf-8 when encoding private-key-value
