Replace regular expressions for path templating

[glowcloud]

Instead of using regular expressions to replace URL path variables, we should use:

It looks like this affects at least two places:

swagger-js/src/execute/swagger2/parameter-builders.js

Line 54 in 10cbc2e

req.url = req.url.replace(new RegExp(`{${parameter.name}}`, 'g'), encodeURIComponent(value));

swagger-js/src/execute/oas3/parameter-builders.js

Line 24 in 10cbc2e

req.url = req.url.replace(new RegExp(`{${name}}`, 'g'), styledValue);
