[Update]: Improve coverage

[Mohsen-T]

• refactored the skip files array generation process in the .solcover.js
• solidity-coverage does not offer native support *.sol.
• implemented a programmatic function to dynamically generate the skip files array based on folder names.
• defined the depth of coverage

@Mohsen-T to reach this point, create a test in test/validators/remove.ts trying to remove an existing validator (publicKey correct) with the wrong parameters (msg.sender or operatorIds)

[mtabasco]

@Mohsen-T please create a test to fire the revert PublicKeysSharesLengthMismatch

In ClusterLib.sol seems this line is skipped. The test Register validator in a new cluster with incorrect input data passes the wrong cluster data. Maybe you can pass specifically that parameter wrong to include that line in the coverage? thanks

[mtabasco]

In OperatorsLib.sol, we haven't tested ExceedValidatorLimit error😱

[mtabasco]

ProtocolLib.sol Please test the MaxValueExceeded error

[mtabasco]

ValidatorLib.sol Please test InvalidOperatorIdsLength and InvalidPublicKeyLength

[mtabasco]

please skip contracts/upgrades from the coverage test
