Swap module scaffolding and params (#922)
* swap module scaffolding

* global swap fee

* can't think of a reason for begin blocker; removing for abci.go for now;

* test pair types; refactor pair name logic; simplify pairs validation and
fix stack overflow error

* check comparison

* use test package

* init swap module genesis

* add basic marshall tests

* remove reward apy from pairs

* fix integration helpers

* use max swap fee constant; fix validation of swap fee; add tests to
cover param validation and param set setup

* use noerror over nil

* start genesis tests

* test param set validation mirrors param validation

* add genesis tests

* remove print statement

* add subtests for genesis test cases; add extra querier test for unknown
route; add keeper params testing

* add spec

* update swagger

* find replace hard -> swap in comments

* remove unused method

* rename pairs to allowed pools; pool is more commonly used, and
allowedPool makes it more clear what swap parameter is for.  In
addition, we won't conflict with Pool data structure for storing a
created pool in the store.

* remove generated link

* missed spec rename

* validate token order for allowed pools

* fix swagger

* json should be snakecase; change allowedPools to allowed_pools
