chore: update tslint to latest version (#2952)

* chore: update tslint

* Updates TSLint to the latest version.
* Due to some breaking changes we had to temporary disable the `no-inferrable-types` rule. Need to revisit once palantir/tslint#2158 is addressed.

References #2175

* Use custom tslint rule
